Dijagnostika ponašanja pogonskih grupa na rotornom bageru / Behaviour diagnostics of drive units on bucket wheel excavators
(Asocijacija za dizajn, elemente i konstrukcije - ADEKO, Niš i Univerzitet u Novom Sadu - Fakultet tehničkih nauka, Novi Sad, 2007)
Dijagnostika ponašanja pogonskih grupa na rotornom bageru je sublimacija analitičkog preseka stanja, numeričkog modela preko metode konačnih elemenata i izmerenih vibracija na karakterističnim mestima pogonskih grupa, ...
Variable Coefficients Model for Drying Processes with Conductive Heat Supply
(Taylor & Francis Inc, Philadelphia, 2009)
The proposed model is for heat and mass transfer inside a layer of moist material placed on hot isothermal surface. The relevant thermophysical properties of the material are considered as fully dependent on local temperature ...
Analiza prigušenja konstrukcije tipa ljuske od legure titana u poređenju sa konstrukcijom od legure aluminijuma / Analysis of structural damping of titanium alloy shell structures as compared with that of aluminium alloy structures
(Institut za ispitivanje materijala, Beograd, 2009)
U ovom radu se razmatra mehaničko ponašanje konstrukcije od legure titana sa aspekta određivanja osnovnih dinamičkih karakteristika. Analiziran je numerički model za konstrukcije legure titana tipa ljuske (osnovni konačni ...
Microstructure Changes of Nickel-Base Superalloys Induced by Interaction with Femtosecond Laser Beam
(Polish Acad Sciences Inst Physics, Warsaw, 2009)
The investigation was performed on nickel-base superalloys, with nickel being the most influential alloying ingredient. After thermo-mechanical preparation and corresponding processing, femtosecond laser beam machining has ...
Micromechanical estimates of the critical values of j-integral for the steel of steam pipelines
(Springer, New York, 2009)
We analyze the level of damage to 14MoV63 steel for steam pipelines under the conditions of crack-growth initiation according to the mechanism of ductile fracture. The state of the material after service for about 100,000 ...
Transition temperature and fracture mode of as-castand austempered ductile iron
(Wiley, Hoboken, 2008)
The ductile to brittle transition temperature is a very important criterion that is used for selection of materials in some applications, especially in low-temperature conditions. For that reason, in this paper transition ...
Analiza oštećenja i naponskog stanja poluga mlinova za ugalj termoelektrane na fosilna goriva / Damage and stress state analysis of fossil fuel power plant coal mill crank
(Visoka tehnička škola strukovnih studija, Beograd, 2006)
U radu je dat prikaz oštećenja koja se javljaju kod poluga mlinova za ugalj termoenergetskih postrojenja u uslovima eksploatacije. Nastala oštećenja mogu da budu takvog karaktera da poluge mlinova za ugalj izgube svoju ...
An experimental verification of numerical models for the fracture and fatigue of welded structures
(Institute of Metals and Technology, 2007)
By allowing a more detailed analysis, numerical modelling has an important role to play in the development of structures. However, the results of a numerical model's analysis have to be verified with an experimental analysis ...
The effect of annealing temperatures and cooling rates on microstructure and mechanical properties of investment cast Ti-6Al-4V alloy
(Elsevier Sci Ltd, Oxford, 2006)
Production of investment castings of titanium alloys was considerably increased during last years due to the significant cost savings compared to complicated machined parts. However, the disadvantage of as-cast titanium ...
Modelling of ductile fracture initiation in strength mismatched welded joint
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
In this paper, the effect of strength mismatch and width of the welded joints oil the stress-strain distribution in the crack tip region has been discussed. The single-edge notched bend (SENB) specimens (precrack length ...
