AB  - Within the theory of thermo-elasticity, the temperature field of thin plates 
is commonly defined via two parameters: temperature in the mid-plane and 
linear temperature gradient normal to the mid-plane. First, the paper 
analytically proves the justification of that assumption in machine 
structures. Then, in an analytical closed form, applying the integral 
transformation method, the thin plate deflection caused by a constant 
temperature gradient is defined. It is shown that, in that case, the plate 
deflection does not depend on its thickness but only on the plate 
dimensions in the mid-plane. Analytically defined values are compared to 
corresponding values obtained by applying the thin plate finite element, 
where the temperature field is described using the two mentioned 
parameters. This finite element is defined and programmed within the 
Komips program package. The influence of the temperature gradient on 
the behavior of constructions mostly depends on the type of material. That 
is why the behavior of some structural elements made of brass, steel, and 
concrete is analyzed in this paper.

AB  - The paper presents analytical and numerical determina-tion of the equivalent stress and strain of the open section thin-walled ‘’ cantilever beams loaded with torsion. Ana-lytical calculation was used to calculate the equivalent stress and strain values for the model encastred across the entire cross-section at one end, while the other end is free (model 1). The finite element method is applied for the calculation of the same ‘’ cantilever beam model exposed to torsion, and the stress and strain values are obtained by numerical calculation. Numerical simulations have been performed using KOMIPS software. Analytical and numerical results are compared and discussed. In this paper, a numerical model for constrained torsion is also created in ABAQUS® and SolidWorks® software. A cantilever beam with an omega profile is encastred at one end, while at the other end there is a welded plate (model 2). Numerical models are created, and static calculation is done using the finite element method. The zones of stress concentration are identified and presented. Finally, the equivalent stress values of models 1 and 2 are compared. Conclusions obtained by examining this type of structures may be involved in the design process of new similar structures. The findings obtained during the implementation of this work can be directly applied to iden-tify the behaviour of real structures in their working condi-tions.

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  - The aim of this paper is to present the application of thin-walled beams on cargo raft load-bearing structure from the aspect of strength and reliability. The beams have an open cross section. Analytical and numerical determination of equivalent stresses and deformations of open section thin-walled ‘U’ and ‘Z’ cantilever beams, loaded with torsion, is presented. Work is divided into three parts. In the first part, equivalent stress and deformation are obtained analytically for cantilever beam model in the whole cross section. In the second part, the finite element method is applied in beam models, and the results are compared with the analytical calculation. The third part presents the profiles installed in load-bearing structures of vessels (rafts) and solutions are shown to apply results of the presented analyses in order to increase reliability. Finally, the design calculation of the raft load-bearing structure is shown.

AB  - The electrochemical behaviour of the P/T91 steel with martensitic microstructure as well as its behaviour 
in cavitation conditions has been investigated in this study. The electrochemical techniques used to 
analyze corrosion behaviour include Linear Polarization Resistance (LPR), Electrochemical Impedance 
Spectroscopy (EIS) and Linear Sweep Voltammetry (LSV). Corrosion rate determination was performed 
in a solution that simulates the industrial atmosphere. In laboratory conditions, ultrasonic vibratory 
cavitation test set up (stationary specimen method) has been applied on specimens made of P/T91 steel. 
Scanning electron microscopy technique has been applied to analyze the morphology of the eroded 
surfaces and to interpret the results of the cavitation tests. Test results have shown that, from the point of 
view of corrosion, P/T91 steel has a favourable chemical composition but the unfavourable lamellar martensite microstructure. Also, the morphology of surface damage from cavitation of P/T91 steel 
resembles the features of the fatigue failure. In order to evaluate the resistance to cavitation of 
investigated material, its cavitation rate was compared with those of some other martensitic steels used in 
fabrication of various industrial components for application in thermal power plants.

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  - 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.

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 
elements subjected to several loading cases. Optimization parameters have been determined by 
Lagrange’s multipliers method. The obtained results are used for numerical calculation.

AB  - Razmatran je jedan pristup optimizaciji tankozidih otvorenih poprečnih preseka oblika Z - profila, izloženih savijanju i ograničenoj torziji. Za data opterećenja, materijal i geometrijske karakteristike, problem se svodi na određivanje minimalne mase, odnosno minimalne površine poprečnog preseka konstruktivnih tankozidih poprečnih preseka izabranog oblika. Površina poprečnog preseka je izabrana za funkciju cilja. Uvedena su naponska ograničenja. Primenjuje se Metoda Lagranžovog množitelja. Rezultati analitički dobijenih jednačina za matematički model, numerička rešenja, kao i ušteda u masi, izračunati su za tri slučaja opterećenja. Neki rezultati su provereni primenom programa COSMOS.
AB  - One approach to the optimization of a thin-walled open section Z-beam subjected to the bending and to the constrained torsion is considered. For given loads, material and geometrical characteristics, the problem is reduced to the determination of minimum mass i.e. minimum crosssectional area of structural thin-walled beam of the chosen shape. The area of the cross-section is assumed to be the objective function. The stress constraints are introduced. The Lagrange multiplier method is applied. Solutions of analitically obtained expressions for the mathematical model, numerical solutions, as well as the saved mass, are calculated for three loading cases.

AB  - Membrane walls are very important structural parts of water-tube boiler construction. Based on their specific geometry, one special type of finite element was defined to help model the global boiler construction. That is the element of reduced orthotropic plate with two thicknesses and two elasticity matrixes, for membrane and bending load separately. A global model of the boiler construction showed that the high value of stress is concentrated in plates of the buckstay system in boiler corners. Validation of the new finite element was done on the local model of the part of membrane wall and buckstay. A very precise model of tubes and flanges was compared to the model formed on the element of a reduced orthotropic plate. Pressure and thermal loads were discussed. Obtained results indicated that the defined finite element was quite favorable in the design and reconstruction of the boiler substructures such as a buckstay system.
