AB  - Industrial robots are used for high-precision tasks and in intensive production.  One of the most reliable methods for monitoring robots’ work is vibrodiagnostics, which provides recommendations and maintenance procedures, and also serves as a reliable diagnostic method for determining the causes of industrial robot failures. Connection of robot and the supporting structure is very important and it affects on dynamic behavior of the robot. This paper presents the process of diagnosing dynamic condition of the structure with painting robots, after the failure of the robot motion reducer. To analyze the causes of the failure, a numerical analysis was performed, which included: static calculation, dynamic calculation, determining transfer function in frequency domain and reinforcement factors. Supporting structure has very low eigen-frequencies (3,5 to 9.5 Hz), it cannot accept inertial forces and large deformations and resonant behavior occur. Using FEM analysis is shown that the behavior of the structure is unfavorable because 20 eigen-oscillations had a frequency less than 17 Hz, and all are located in the robots’ working space. Determination of the transfer functions showed that the dynamic gain factor in all three directions of the excitation force is extremely large, while the corresponding frequencies are 5 ÷ 20 Hz.  It was determined that the main problem was the rigidity of the supporting structure.

AB  - Stereooptics method have been successfully used in biomechanical studies of dental models. The aim of this study was to investigate, on the basis of functional deformities, the distribution of occlusal loads on the casts of a partially-edentulous mandible without and with dedicated copings. Precise measurement of strain and displacement of partially-edentulous mandibular control and experimental casts were provided by the digital image correlation method and ARAMIS software. Simulated loads ranged from 0 to 1000 N. Displacements and deformations of abutment teeth within the control cast of a partially-edentulous mandible were 0.48% for incisor without coping, 10.29% for canine without coping, and 6.64% for premolar without coping, and within the experimental cast of a partially-edentulous mandible they were 0.29% for incisor with coping, 7.007% for canine with coping, and 4.98% for premolar with coping. Wilcoxon matched pairs signed ranks sum test was not statistically significant for the majority of the examined parameters, except for the differences between deformations of teeth and copings under pressure p  lt = 0.05. When loading the abutment teeth, the distribution of strain through the remaining tooth substance is specific and various. Abutment teeth covered by protective copings are more resistant to loads.

AB  - Boilers are one of the most used units for both heat generation plants and industry systems. Their operation is subjected to different working loads and maintenance requirements. Exploitation experience points out critical boiler zones where failures and break downs typically occur. This paper analyzes critical zones in hot water fire-tube boiler. Experimental procedure was performed on the model of this type of boilers and its critical element. The tube plate of hot water boiler was identified as the most critical one. Experimental analysis and numerical model verification were performed using Aramis system based on 3-D digital image correlation method. Numerical analysis was done in ANSYS software package and verification of results was done based on measurements obtained by strain gauges and local measurements performed by the Aramis system. Stress-strain analysis indicates the critical zones of boiler tube plate. The character of change parameters such as strain and stress occurring in the critical zones can be verified both by experimental and numerical data. The paper presents a novel approach in experimental and numerical analyses that can be conducted in similar units and used for existing unit optimization, as well as for new product testing on different loads and provide opportunity for further development and improvement for practical industrial application.

AB  - Hot water boilers are most commonly used devices in thermal and industrial plants for heat production. Boilers elements are exposed to high pressures and temperatures during boiler operation. Non-stationary working regimes of boiler may lead to breakdowns and fatigue of boiler elements. There are numerous cases of breakdowns of such units, which lead to reduced reliability and safety of the plant. In order to avoid this state, certain investigation should be made that would examine the influence of different regimes on the boiler structure. Lack of available data concerning the temperature as well as stress-strain field in boiler elements led us to perform such kind of experiment. This paper presents results of numerical analysis performed on the modelled boiler. Validation of the numerical model was performed based on experimental results obtained using DIC (Digital Image Correlation) method by using Aramis system. The character of parameters change, such as strain and stress, occurring in the critical zones of boiler elements can be verified both by experimental and numerical results. In this paper the novel approach of experimental and numerical analysis is presented. The method can be used and conducted in similar units for testing on different loads or working regimes, as well as to improve the safety and reliability of similar pressure vessel units.

AB  - Hot water boilers, especially boilers with fire tube where the combustion takes place, are widely used in process industry. Elements of the boiler are exposed to high pressures and temperatures during boiler operation. Exploitation experience indicates constant and permanent breakdowns occurring as a result of accidental states of individual boiler elements. Studies done before in this field indicate certain critical boiler elements that may have influence on the reliability and safety of the entire unit. In order to avoid this state, certain investigation should be made that would examine the influence of different regimes on the boiler structure. Lack of available data concerning the temperature as well as stress-strain field in boiler elements led us to perform such kind of experiment. This paper presents results of numerical analysis performed on the modelled
boiler. Validation of the numerical model was performed based on experimental results obtained using 3D Digital Image Correlation analysis. This paper analyses critical elements of the hot water boiler by experimental data obtained from its model and improved numerical model in order to analyze constrains and loads the model is exposed to and to have fully-covered stress-strain field obtained from experimental data.

AB  - This paper describes pipeline stress analysis, primarilybranch junctions, as a structural element in hydro-power plants. Pipelines are exposed to internal pressure,which is present under working conditions. Analysis of stresses in the pipeline of the hydropower plant is based on analytical, numerical, and experimental methods In this paper, we will define the critical elements of the pipeline. After that, we will determine critical areas in the branch junction, under experimental conditions, where strain gauges should be installed. The obtained resultsshow that a boiler formula can be efficiently applied in the stress analysis. Also, a correlation between the internal pressure and the maximum circumferential stresses in the elastic zone is given. In the final sections of the paper, the limit value of the internal pressure as a load for which stress in the zone of plasticity appears and the safety factor of the branch junction in the exploitation conditions are determined. The contribution of this work is the unification and deepening of the topic related to the problem of the testing othydro-power structural elements.

AB  - The paper presents a procedure for modeling an orthotropic thin plate finite element so to have an equivalent structural response as the steel stiffened plate of same overall dimensions. New, equivalent element, homogenizes the structural properties of plates and stiffeners in element's stiffness matrix. By use of such elements, a significant reduction in overall size of a global finite element model of large stiffened panel structures could be achieved. The algorithm of proposed procedure is fully explained and, as an example, applied to a standard global model of steel ship hull structure. Structural response comparison is made between reduced model made of newly defined thin finite elements and conventional ones. Advantages are emphasized and remedies of some recognized shortcomings are suggested.

AB  - Examination of strain field underneath the teeth and bone structure of mandible for ‘’in vitro’’ conditions requires
thorough preparation of the examinee and equipment. For the purpose of examination of different regions of
partly-edentulous mandible, the design solutions for examination of strain fields located on the determined
points have been shown for different types of compensations.
Strain measurement was performed using contactless optical 3D system ARAMIS 2.0. Mandible model with
several remaining teeth was additively manufactured using SLA technology. The measurement of acting force
was performed using a dynamometer, with the maximum applied force intensity of 800N. The results of this
study showed that developed experimental setup enables comparison of influence of different teeth geometries
and metal compensation designs to the selected areas of artificial partly-edentulous mandible resulting in
specific strain distribution.

AB  - The paper presents an analytical closed-form solution to the problem of dynamic change in 
the temperature field of a steel sample model during a short-term heating up and thereafter intense heat removal. It is demonstrated how a relatively complex thermal problem can be solved analytically based on differential equation that describes the temperature field. Differential equation that describes the temperature field is formed via the power of several heat sources with limited action time, as shown mathematically by applying the Dirac and Heaviside functions. In the present paper the example provided includes two heat sources. In accordance with boundary conditions the differential equation is solved by applying the finite Fourier transforms and Laplace transform. Based on obtained analytical solution of the problem, a numerical model was created corresponding to the simulation of steel sample heating on a thermomechanical welding simulator. The welding thermal simulator is a device used to achieve controlled heating and cooling, similar to the one in welding. Analytically calculated temperature fields were utilized to obtain the strain distribution in the heat source environment by applying the finite element method.

AB  - The present paper describes numerical and experimental methodology for the analysis of stress and deformation state in structural elements with geometrical discontinuities. The research is based on structural elements of the connecting lug type. The stress and deformation state was determined as the contact area size between the axle and the connecting lug was changing. Numerical analysis was conducted by applying the finite element method in a ''KOMIPS'' software package. Experiments were performed at the Laboratory for stress and deformation measurements, Faculty of Mechanical Engineering, University of Belgrade, using ''GOM'' equipment and ''ARAMIS'' software application (DIC). This paper demonstrates how it is possible to anticipate the results by applying FEM. A short review of current research in the field of structural elements with geometrical discontinuities is given within the framework of the paper.

AB  - Koncentracija napona u uglu kvadratnog otvora u ploči je poznata činjenica. Najčešće se uzima da je najveća koncentracija napona u samom temenu ugla (na ugaonoj koordinati od 45 stepeni u slučaju kvadratnog otvora). Rigoroznije analize, ipak, prikazuju da ovo baš nije najtačnije. Iako maksimalni napon nikada "ne napušta" ugao, u nekim proračunima koncentracije napona, ozbiljnije analize ovog fenomena dobijaju na značaju. U ovom radu prikazani su i poređeni rezultati analitičke, numeričke i eksperimentalne analize tačne pozicije koncentracije napona u uglu otvora, u slučaju ploče pri istezanju.
AB  - Development of stress concentration in the corner zone of rectangular plate opening is a well-known fact. It is usually literally taken that the largest stress concentration factor (SCF) occurs exactly in the corner (at angle coordinate of 45 degrees in case of square opening). More rigorous analyses, however, reveal that this is not perfectly true. Although maximum stress never really "leaves the corner", for some hot-spot analyses, more scrupulous investigation of this phenomenon has significance. In this paper, results of some analytical, numerical and experimental investigations of this topic, for plate in tension, are presented and compared.

AB  - The possibilities of testing real constructions strength are often limited, especially in case of large constructions. Testing on the model, instead of the actual construction, results in a great saving of money and time. Sub -scaled model of the construction of the substructure, the slewing platform and the lower part of the pylons of the bucket wheel excavator SchRs630 is made. Numerical calculations (using Finite Element Method) and experimental testing of the model were performed. Experimental testing is performed using classical strain gauge method and Digital Image Correlation Method (Aramis system). Once again, advantages of Digital Image Correlation method compared to classical measurement methods are confirmed. The negative impact of conventional manufacturing methods in some zones is noticed.

Sub-sized model of the pipe branch of A6 third pipeline at Hydropower Plant Perućica, Nikšić was made in order to be subjected to a detailed experimental testing.

Based on the pipe branch model behaviour, and after determination of relation between the model and the real structure, maximum calculated internal pressure value to which the structure may be subjected in exploitation is assessed. Besides, weak spots on the structure were verified by obtaining the same results through experiment and calculation, which gives good guidelines for monitoring of this structure during usage, since it is possible, by using this analysis, to decrease the number of measurement locations for monitoring (in order to control exactly those measurement locations, which proved to be the most endangered).

It was determined that the inertial forces caused by bucket wheel boom and counterweight boom masses while breaking slew drive cause the stress concentration in this spot. To complete the whole picture of the structure behaviour dynamic analysis was performed. Based on calculation and distribution of potential and kinetic energy on oscillation modes, using the reanalysis method, redesign of this part of the structure was proposed. The stress was reduced by over 20 % by the proposed redesign solution.

AB  - Based on experience from the testing of the mining stacker in the copper mine in Bor, a practical procedure of frequency simulation of the enforced vibration of the structure was demonstrated. Modelling of the excitation was performed by the harmonic function of the eccentric mass of the belt conveyor drive. The paper shows how the drive frequency excitation affects the amplitude of vibration of the supporting structure. From this, the idea is presented - an algorithm for software that would allow for keeping the dynamic properties of the members of the structure within controlled range. An experiment for accelerating the structure and its FFT analysis in the frequency domain was performed. Dynamic modelling of the structure allows obtaining the objectivised concept of the measurement system for monitoring based on the given level of dynamic sensitivity of the parts of the structure.

AB  - Bucket wheel excavator ERs 1250 has been in operation for over 30 years in the Grae'anica-Gacko mining basin. It is operating in very hard working conditions due to exploiting very solid material, which has adverse effects on the behavior of the whole structure. Bucket wheel excavator boom is a single tube approximately 20 m long. The crack was detected in a cylindrical root of the boom tube at nearly 270 degrees of its circumference. Finite element method was applied in calculations and the first calculation was performed for the complete usage of engine power (the least favorable case), but it didn't indicate the possibility of crack occurrence. Based on exploitation measurements of stress and accelerations, additional simulations of loading were performed (horizontal and vertical unit loads) that could cause the crack. Numerical analysis has shown that the horizontal force causes the initial crack. Measurements and realized loading cycles indicated that the effect of material fatigue is extremely strong. That is why the fatigue is the cause of a considerable crack increase. Based on numerical investigation of the failure, rehabilitation and reparation of the wheel boom were done in the manner as presented in the paper. So, bucket wheel excavator has been operating successfully for a number of years.

AB  - Globe valves are one of the most widely used industrial fittings. Due to variety in globe valve application, different loadings occur in its working life (static, dynamic, thermal etc.), but the most dominant one is internal pressure. This paper presents the analysis of standard globe valve housing under the internal pressure using 3D Digital Image Correlation method, Finite element analysis and calculation according to EN standard. Experimental analysis was focused on determining mechanical properties of critical areas, i.e. on local areas of globe valve housing with high geometrical discontinuities. Experimental system consists of cameras for 3D displacement and strain analysis and software Aramis. Models designed using FEA are verified through the experiment, while at the same time the possibility of using Aramis system for these constructions has been proven. It is found that the predictions from the model agree well with experimental results as the result differences between two methods in the area of the highest strain values vary below 30 %, which is satisfactory for engineering application. Experimental and numerical results demonstrate that the experimental method is adequate for solving geometrically complex problems and provides an opportunity for further development and improvement for practical industrial application.

AB  - The linear buckling phenomenon is obviously very important for stability of compressed supports. The determination of buckling resistance is an important characteristic of the design of steel structure. Besides, the presence of stiffeners in structural plate elements has a vital role in order to increase critical buckling load capacity. However, these stiffeners cause a redistribution in buckling behaviour in terms of local and global buckling. In this paper the transverse and longitudinal stiffeners were employed on a real beam-column structure to maximize the critical buckling loads. The objective is to find the optimum geometry of stiffeners. Based on the finite element method, a numerical model is made using the Abaqus program in order to observe the critical buckling capacity. The results showed that the local critical buckling has been significantly affected by stiffener's position in the case of transverse stiffeners, but little effect is observed on the critical local and global buckling in the case of longitudinal stiffeners.

Analysis of pipe branch model stress distribution was carried out by using finite element method and experimental methods. Finite element method defined 3D pipe branch model. Numerical calculation defined critical locations on model, i.e. locations with the greatest stress concentration. Strain gauges were placed on identified critical locations. Measured stress values confirmed values obtained by using numerical calculation. Experimental measurements were also taken by using new digital image correlation (DIC) method. DIC method is an optical non-contact method that can provide full 3D stress field and enables better understanding of complex structures such as pipe branches. The aim of this paper was to determine stress concentration factor for the pipe branch model by using numerical and experimental analysis.

subjected to the bending and to the constrained torsion. The particular attention is paid to the 
structural optimization methods. The optimal weight of the structures is obtained starting from 
some initial values of thicknesses and cross-sectional areas. The analytical and numerical 
approaches are derived for structural elements of different shapes of the open cross-section
