AB  - Owing to their good mechanical properties, titanium based alloys are used for machine parts and devices that operate in demanding regimes and environmental conditions. Laser shock peening (LSP) is an innovative technique for improvement of the surface and mechanical characteristics of the material. In this paper, LSP is employed for additional improvement of already good characteristics of Ti- alloy. Laser shock peening is performed on alloy surface, with and without protective and transparent layer and obtained microstructure, surface characteristics and mechanical properties are compared. LSP improved the surface topology and microhardness of material, producing overall better results when the Ti-alloy surface was coated by transparent and protective layer.

AB  - Analysis of stress and strain at the tip of fatigue crack by means of linear elastic fracture mechanics has led to the formulation of well known Paris’ equation which brings fatigue crack growth speed (da/dN) and stress intensity factor range at the crack tip (ΔK) in a relation.For the purpose of determining the fatigue crack growth parameters of titanium alloy Ti-6Al-4V a standard Charpy specimen was used and a three - point bending method on a resonating high - frequency pulsator. Standard fracture mechanics tests on notched specimens can provide insight into the fracture behaviour of materials under constrained deformation, i.e. under a threedimensional stress state. Specimens were taken from a plate with dimensions of 80x300x30 mm, made of Ti6Al-4V alloy. In order to monitor the increment of crack length, strain gauges were applied to the specimens.
The obtained frequency was in the range from 215 to 235 Hz, while the stress ratio was R=0.1. Average load
and it’s amplitude were registered with the ±3 Ncm accuracy. All tests were conducted at room temperature.
Test results are intended for the finite element method (FEM) and extended finite element method (XFEM)

AB  - An increasing diversity of operations and different materials, as well as different working conditions lead to various construction solutions. Structural design is the preparation of structures that shall be efficient in fulfilling anticipated exploitation conditions, both economically and safely, i.e. there will be no damage resulting in the loss of structural functionality in service. In practice, however, there are fractures that can occur during construction, assembly, and exploitation. Fracture may be caused by overloads, by static fracture, or by dynamic loads, and by fatigue. Upon calculation of static structural durability, normal and tangential stresses are taken into account, while the dynamic durability calculation defines structural resistance to crack formation and its propagation under dynamic loading. The aim of this paper is to demonstrate the possibility of applying fracture mechanics to structural integrity assessment. To this end, the basic concepts of linear elastic fracture mechanics will be explained.

AB  - Fatigue crack growth in hip implant has been analysed using the extended finite element method. Toward this aim, the three-dimensional finite element model is created and used in ABAQUS and Morfeo/crack add-in for ABAQUS to simulate fatigue crack growth from initial value up to the critical point. Initial crack dimensions are assumed according to the experience with failures of hip implants, whereas the final, critical value was estimated using data for fracture toughness obtained by experimental testing of hip implant made of Ti-6Al-4V alloy. Results for the equivalent stress intensity factor and number of cycles in each of 40 steps of fatigue crack growth are presented and analysed, indicating the point of unstable crack growth.

AB  - U okviru rada su predstavljeni principi i primeri savremenih eksperimentalnih metoda za određivanje parametara mehanike loma. Metodologija analize i određivanja parametara mehanike loma obuhvatila je analizu ponašanja metalnih materijala u odnosu na lom primenom modifikovanih epruveta mehanike loma, sa inicijalnom prslinom i zateznim opterećenjem, i imala je za cilj pre svega određivanje karaktera tih procesa u slučaju problema tankih pločica, uz korišćenje osnovnih postulata mehanike loma. Metodologija uključuje primenu eksperimentalnih postupaka mehanike loma definisanih standardima, uz primenu metode za trodimenzionalno stereoskopsko merenje mehaničkog ponašanja materijala. Pomoću sistema za korelaciju digitalnih slika (Digital Image Correlation, DIC) za ispitivanje deformacija i pomeranja u materijalu ispitani su parametri mehanike loma metalnih materijala, pre svega epruveta od 316L nerđajućeg čelika i titan legure Ti-6Al-4V. 3D optički sistem GOM i softver Aramis su korišćeni za izvođenje eksperimentalne analize na pripremljenim epruvetama. Pošto se ovaj sistem koristi za merenje deformacija i parametra pomeranja otvaranja vrha prsline CTOD na modifikovanim kompaktnim epruvetama za zatezanje C(T) i epruvetama sa zarezom, dat je i kratak pregled mernih procedura i procesiranja rezultata, kao i moguće primene ovog sistema. Prikazani rezultati daju pregled polja deformacija i pomeranja tokom otvaranja vrha prsline, rasta prsline i u trenutku loma epruvete, što nije moguće putem tradicionalnih metoda merenja. Analizom rezultata pokazano je da je sa velikom preciznošću moguće izmeriti pomeranja tokom otvaranja vrha prsline i dobiti CTOD parametar. Rezultati pokazuju da odabrana metoda pruža dobre rezultate u analizi mehaničkog ponašanja i određivanju parametara mehanike loma metalnih materijala.
AB  - The principles and examples of state-of-the-art experimental methods for measuring the fracture mechanics parameters are presented in this paper. The methodology of experimental analysis of the fracture mechanics parameters includes investigation of fracture behaviour of metallic materials using modified specimens with initial crack under tensile load, with the primary goal of determining the characteristics of fracture processes for the case of thin plates, using basic fracture mechanics postulates. The methodology also includes the application of experimental fracture mechanics procedures as defined by standards, using three-dimensional stereo-metric mechanical behaviour measurement methods. Fracture behaviour of metallic materials, mainly 316L stainless steel and titanium alloy Ti-6Al-4V specimens, is analyzed by using a digital image correlation (DIC) system for measuring strain and displacement in the material. GOM three-dimensional optical system and Aramis software are used to perform experimental analysis of selected specimens. As this system is used to measure strain and crack tip opening displacement (CTOD) parameter on the modified compact tension specimen C(T) and notch specimens, a basic review of measuring procedures and result processing is given, alongside other possible applications for this system. The presented results show strain and displacement fields during crack tip opening, crack growth, and the moment of fracture of specimens, which are not possible using traditional measurement methods. The analysis of results shows that it is possible to measure displacements during crack tip opening with a great precision, and thus obtain the CTOD parameter. The results show that the selected measuring method obtains good results in the analysis of mechanical behaviour and fracture mechanics parameters of metallic materials.

abstract = "U okviru rada su predstavljeni principi i primeri savremenih eksperimentalnih metoda za određivanje parametara mehanike loma. Metodologija analize i određivanja parametara mehanike loma obuhvatila je analizu ponašanja metalnih materijala u odnosu na lom primenom modifikovanih epruveta mehanike loma, sa inicijalnom prslinom i zateznim opterećenjem, i imala je za cilj pre svega određivanje karaktera tih procesa u slučaju problema tankih pločica, uz korišćenje osnovnih postulata mehanike loma. Metodologija uključuje primenu eksperimentalnih postupaka mehanike loma definisanih standardima, uz primenu metode za trodimenzionalno stereoskopsko merenje mehaničkog ponašanja materijala. Pomoću sistema za korelaciju digitalnih slika (Digital Image Correlation, DIC) za ispitivanje deformacija i pomeranja u materijalu ispitani su parametri mehanike loma metalnih materijala, pre svega epruveta od 316L nerđajućeg čelika i titan legure Ti-6Al-4V. 3D optički sistem GOM i softver Aramis su korišćeni za izvođenje eksperimentalne analize na pripremljenim epruvetama. Pošto se ovaj sistem koristi za merenje deformacija i parametra pomeranja otvaranja vrha prsline CTOD na modifikovanim kompaktnim epruvetama za zatezanje C(T) i epruvetama sa zarezom, dat je i kratak pregled mernih procedura i procesiranja rezultata, kao i moguće primene ovog sistema. Prikazani rezultati daju pregled polja deformacija i pomeranja tokom otvaranja vrha prsline, rasta prsline i u trenutku loma epruvete, što nije moguće putem tradicionalnih metoda merenja. Analizom rezultata pokazano je da je sa velikom preciznošću moguće izmeriti pomeranja tokom otvaranja vrha prsline i dobiti CTOD parametar. Rezultati pokazuju da odabrana metoda pruža dobre rezultate u analizi mehaničkog ponašanja i određivanju parametara mehanike loma metalnih materijala., The principles and examples of state-of-the-art experimental methods for measuring the fracture mechanics parameters are presented in this paper.

AB  - In this paper are presented experimental analyses of the behaviour of 316L stainless steel in regard to fracture, according to standard methods of investigation on modified tensile C(T) specimens. The S316L alloy is selected for this experimental analysis, often used in many engineering applications. This alloy is not prone to corrosion as other austenitic steels with a higher share of carbon. Results show that material behaviour, in terms of dependence of stress intensity factor (SIF) value relative to thickness of the plate, is necessary to assume with a different model when the specimen thickness is very small. Application of standards in the field of investigation of material resistance to fracture allow simultaneous determination and connection of several fracture mechanics parameters.

AB  - In this paper numerical analysis of hip replacement implant behaviour from a fracture mechanics perspective is presented. It is necessary to understand the fatigue crack initiation and propagation characteristics in order to prevent catastrophic failure of the implant. For the simulation of crack propagation extended finite element method (XFEM) was used, as being one of the most advanced modeling techniques for this type of problem. Short theoretical background information on the XFEM is provided, as well as the representation of crack and the stress intensity factors computation. For chosen titanium alloy hip implants numerical modeling and analysis were done in ABAQUS software. It is shown that is possible to assume hip implant mechanical behaviour to the existence of defects such as cracks by application of numerical simulation crack behaviour. The numerical results illustrate that XFEM is efficient for the simulation of crack propagation in complicated biomedical structures, without the need to re-mesh during the propagation if the finite element mesh is well defined.

AB  - The paper presents a study on the surface modifications of nickel based superalloy Nimonic 263 induced by laser shock peening (LSP) process. The process was performed by Nd3+:Yttrium Aluminium Garnet (YAG) picosecond laser using the following parameters: pulse duration 170 ps; repetition rate 10 Hz; pulse numbers of 50, 100 and 200; and wavelength of 1064 nm (with pulse energy of 2 mJ, 10 mJ and 15 mJ) and 532 nm (with pulse energy of 25 mJ, 30 mJ and 35 mJ). The following response characteristics were analyzed: modified surface areas obtained by the laser/material interaction were observed by scanning electron microscopy; elemental composition of the modified surface was evaluated by energy-dispersive spectroscopy (EDS); and Vickers microhardness tests were performed. LSP processing at both 1064 nm and 532 nm wavelengths improved the surface structure and microhardness of a material. Surface morphology changes of the irradiated samples were determined and surface roughness was calculated. These investigations are intended to contribute to the study on the level of microstructure and mechanical properties improvements due to LSP process that operate in a picosecond regime. In particular, the effects of laser wavelength on the microstructural and mechanical changes of a material are studied in detail.

AB  - Punjene i samozaštitne žice su dodatni materijali koji se poslednjih godina sve više koriste zbog povećane produktivnosti i ekonomičnosti, boljeg kvaliteta spoja i lakšeg rada na terenu. S druge strane, jedan od glavnih nedostataka ovih žica je povećana količina dimnih gasova i nedovoljna istraženost njihove štetnosti, naročito u slučaju samozaštitne žice. Zbog toga se pred nove generacije ovih žica postavlja i ekološki zahtev smanjenja emisije dimnih gasova radi zaštite kako zdravlja zavarivača, tako i okoline. U cilju istraživanja ovog uticaja, ploče čelika mikrolegiranog sa V, Nb i Ti su zavarene metalnom punjenom žicom u zaštitnoj atmosferi Ar+5.9%CO2+1.1%O2 i samozaštitnom žicom. Pri tome su izmerene vrednosti emisije gasova CO, CO2 i SO2, kao i ukupne prašine. Dobijene vrednosti su upoređene kako međusobno, tako i sa maksimalnim dozvoljenim koncentracijama prema važećem standardu. Utvrđeno je da samozaštitne žice, suprotno očekivanjima, ne pokazuju veću toksičnost u odnosu na metalne punjene žice.
AB  - The use of flux cored and self-shielded wires as filler materials for gas metal arc welding is growing constantly due to increased productivity and efficiency, better weld quality and easer operation. On the other hand, one of the major drawbacks of these wires is the increased amount of fumes and gases and insufficient data of their harmful effects, especially in the case of self shielded wire. Therefore, in now days, one of the most important requirements is environmentally and health request for decreased fume and gas emission. In this paper, the plates of steel micro alloyed with V, Nb and Ti, were welded with metal cored wire in shielded atmosphere of Ar+5.9%CO2+1.1%O2 and with self-shielded wire. The concentrations of emitted total dust and gases CO, CO2 and SO2 were measured. Obtained values were compared with permissible exposure limits defined by standard. It was estimated that self shielded wire did not show higher toxicity compare to metal cored wire, what is in the contrast with previous studies.

abstract = "Punjene i samozaštitne žice su dodatni materijali koji se poslednjih godina sve više koriste zbog povećane produktivnosti i ekonomičnosti, boljeg kvaliteta spoja i lakšeg rada na terenu. S druge strane, jedan od glavnih nedostataka ovih žica je povećana količina dimnih gasova i nedovoljna istraženost njihove štetnosti, naročito u slučaju samozaštitne žice. Zbog toga se pred nove generacije ovih žica postavlja i ekološki zahtev smanjenja emisije dimnih gasova radi zaštite kako zdravlja zavarivača, tako i okoline. U cilju istraživanja ovog uticaja, ploče čelika mikrolegiranog sa V, Nb i Ti su zavarene metalnom punjenom žicom u zaštitnoj atmosferi Ar+5.9%CO2+1.1%O2 i samozaštitnom žicom. Pri tome su izmerene vrednosti emisije gasova CO, CO2 i SO2, kao i ukupne prašine. Dobijene vrednosti su upoređene kako međusobno, tako i sa maksimalnim dozvoljenim koncentracijama prema važećem standardu. Utvrđeno je da samozaštitne žice, suprotno očekivanjima, ne pokazuju veću toksičnost u odnosu na metalne punjene žice., The use of flux cored and self-shielded wires as filler materials for gas metal arc welding is growing constantly due to increased productivity and efficiency, better weld quality and easer operation. On the other hand, one of the major drawbacks of these wires is the increased amount of fumes and gases and insufficient data of their harmful effects, especially in the case of self shielded wire. Therefore, in now days, one of the most important requirements is environmentally and health request for decreased fume and gas emission. In this paper, the plates of steel micro alloyed with V, Nb and Ti, were welded with metal cored wire in shielded atmosphere of Ar+5.9%CO2+1.1%O2 and with self-shielded wire. The concentrations of emitted total dust and gases CO, CO2 and SO2 were measured. Obtained values were compared with permissible exposure limits defined by standard. It was estimated that self shielded wire did not show higher toxicity compare to metal cored wire, what is in the contrast with previous studies.",

AB  - Welding is the principal industrial process used for joining metals, but at the same time, it's the significant source of toxic fumes and gases emission. With the advent of new types of welding procedures and consumables, the number of welders exposed to welding fumes is growing constantly in spite of the mechanisation and automation of the process. Having in mind that, in some cases, toxic fumes and gases can be over the respective limits for toxic substances, one of the most important requirements for chosen welding procedure is its harmlessness to the environment. The health aspects associated with welding are complex and the industry is continuing its research to evaluate the effects of the welder's exposure to typical constituents of welding fumes and gases, as well as its impact on what concerns climatic changes. The aim of this paper is to estimate the influence of the type of filler material on the emission of toxic substances, and to show the potential hazards. In order to determine that effect, microalloyed steel has been welded using two different filler materials (metal cored wire and self-shielded wire). The concentrations of emitted total dust, CO2, CO, SO, Mn, Ni, Al, Cr, Cr(VI), Ca and P were measured. By comparing results for both filler materials, it was established that the special attention must be paid to the high concentration of manganese and CO in metal cored wire, as well as high concentrations of phosphorus and aluminum in self-shielded wire. Also, conducted experimental measurements of emission of certain elements did not show higher toxicity of self-shielded wire compare to metal cored wire, what is in the contrast with previous studies.

AB  - In this paper, the AlMg4.5Mn alloy has been welded using tungsten inert gas (TIG) and metal inert gas (MIG) processes with different gas shielding atmospheres. Tensile strength, hardness, impact and fracture toughness, fatigue crack growth parameters (Delta Kth, da/dN), as well as microstructure were determined. By comparing results for different gas mixtures, the main conclusion for TIG welding was that increased helium content has an important effect on toughness and fatigue crack growth parameters, whereas its effect on other mechanical properties is not significant. On the other hand, in the case of MIG welding, adding helium does not affect mechanical properties, except the fatigue crack growth rate. It was also established that adding nitrogen (TIG welding) and oxygen (MIG welding) reduces toughness and increases crack growth rate, so their use in shielding mixtures is not recommended.

In this paper the results of the analytical calculation regarding the strength of the turbine shaft are presented and influence of the corrosive environment, as well as tests regarding the fatigue. Tensile tests under constant amplitude loading were carried out on smooth specimens in order to determine fatigue properties of the base material, as well as bending tests on notched specimens in order to determine fracture mechanics parameters, or correlation between the crack growth rate da/dN and the stress intensity factor ΔK. It has been established that stress values were higher than allowable values, which led to the occurence of many cracks due to fatigue corrosion. One of those cracks caused the fracture.

AB  - Istraživanje uticaja vibracija na promenu zaostalih napona kod sučeono zavarenih čeličnih ploča i promena energije udara u karakterističnim zonama zavarenog spoja analizirana je u ovom radu. Bitan segment, koji se javlja kao posledica zavarivanja, je pojava zaostalih napona u zoni zavarenog spoja. Merenje zaostalih napona je rađeno na sučeono zavarenim pločama koje nisu vibrirane u toku zavarivanja i kod ploča koje su istovremeno zavarivane i vibrirane. Uočeno je da proces vibracija znatno smanjuje nivo zaostalih napona u zoni sučeono zavarenog spoja, odnosno, dolazi do relaksacije i uravnoteženja stanja napona. Ispitivanja energije udara su pokazala da vibracije pozitivno utiču na povećanje ukupne energije udara i kod epruveta sa zarezom u metalu šava i u zoni uticaja toplote. Uočen je i bolji odnos raspodele energije stvaranja i energije širenja prsline, kao važnih komponenti u oceni plastičnosti zavarenog spoja.
AB  - The effect of vibration on the variation of residual stresses in butt-welded steel plates and on the impact energy in characteristic zones of a welded joint is analysed in this paper. An important segment occurring as a result of welding is the phenomenon of residual stresses in the welded joint zone. Residual stress measurements are conducted both on butt-welded plates that were not vibrated during welding and on plates simultaneously welded and vibrated. It is concluded that the vibration process noticeably decreases the level of stresses in the zone of the butt weld, i.e. the result is relaxation and plane stress state. Impact energy tests have shown that vibration favourably affects the total impact energy by increasing it both in specimens notched in the weld metal (WM) and in the heat-affected zone (HAZ). It is also concluded that the correlation between the distribution of crack initiation- and crack propagation energy, as vital components in the assessment of welded joint ductility, is improved.

Merenje zaostalih napona je rađeno na sučeono zavarenim pločama koje nisu vibrirane u toku zavarivanja i kod ploča koje su istovremeno zavarivane i vibrirane. Uočeno je da proces vibracija znatno smanjuje nivo zaostalih napona u zoni sučeono zavarenog spoja, odnosno, dolazi do relaksacije i uravnoteženja stanja napona. Ispitivanja energije udara su pokazala da vibracije pozitivno utiču na povećanje ukupne energije udara i kod epruveta sa zarezom u metalu šava i u zoni uticaja toplote. Uočen je i bolji odnos raspodele energije stvaranja i energije širenja prsline, kao važnih komponenti u oceni plastičnosti zavarenog spoja., The effect of vibration on the variation of residual stresses in butt-welded steel plates and on the impact energy in characteristic zones of a welded joint is analysed in this paper. An important segment occurring as a result of welding is the phenomenon of residual stresses in the welded joint zone. Residual stress measurements are conducted both on butt-welded plates that were not vibrated during welding and on plates simultaneously welded and vibrated. It is concluded that the vibration process noticeably decreases the level of stresses in the zone of the butt weld, i.e. the result is relaxation and plane stress state. Impact energy tests have shown that vibration favourably affects the total impact energy by increasing it both in specimens notched in the weld metal (WM) and in the heat-affected zone (HAZ). It is also concluded that the correlation between the distribution of crack initiation- and crack propagation energy, as vital components in the assessment of welded joint ductility, is improved.",
