Cold weld cracking susceptibility of high strength low alloyed (hsla) steel nionikral 70
(Faculty of Metallurgy, 2014)
In view of the importance of high strength low alloy (HSLA) steels, particularly for critical applications such as offshore platforms, pipeline and pressure vessels, this paper reports on an investigation of how to weld ...
Calculation of maximum tensile and shear forces in restorative materials using finite element method
(Trans Tech Publications Ltd, Durnten-Zurich, 2014)
The purpose of this paper was to determine tensile loading that leads to dental restoration failure, i.e. the critical values of stress. In order to analyze stress distribution within the restoration and tooth, mechanical ...
Finite element modelling of creep process - steady state stresses and strains
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Finite element modelling of steady state creep process has been described. Using an analogy of visco-plastic problem with a described procedure, the finite element method has been used to calculate steady state stresses ...

(Savez inženjera i tehničara Srbije, Beograd, 2014)
U ovom radu se analizira verovatnoća greške po simbolu za M-arnu ne-koherentnu frekvencijsku modulaciju (M-ary Frequency Shift Keying, MFSK) signala u ambijentu frekvencijsko-neselektivnog sporog Rician fadinga i prijemnika ...
Influence of friction stir welding parameters on properties of 2024 t3 aluminium alloy joints
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The aim of this work is to analyse the process of friction stir welding (FSW) of 3 mm thick aluminium plates made of high strength aluminium alloy - 2024 T3, as well as to assess the mechanical properties of the produced ...
Identification of low cycle fatigue parameters of high strength low-alloy (hsla) steel at room temperature
(Croatian Metallurgical Soc, Zagreb, 2014)
Low cycle fatigue test was performed in ambient atmosphere at room temperature. cycle loading of material, in case of High strength low-alloy steel, entails modifications of its properties and in this paper is therefore ...
Analysis of Composite Shrinkage Stresses on 3D Premolar Models with Different Cavity Design using Finite Element Method
(Trans Tech Publications Ltd, Durnten-Zurich, 2014)
Local polymerization stress occurs due to polymerization shrinkage of resin based composites adhesively bonded to tooth tissues. Shrinkage causes local displacements of cavity walls, with possible occurrence of micro-cracks ...
Failure prediction of gas and oil drilling rig pipelines with axial defects
(Elsevier Science Bv, Amsterdam, 2014)
Working conditions of casing pipes in drilling rigs can significantly influence the initiation and development of damage in the material, and therefore also the safe service of the entire system. In this work, an integrity ...
