Prediction of ductile fracture initiation using micromechanical analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
In the paper ductile fracture initiation analysis of low-alloyed ferritic steel has been made by application of two micromechanical models: the Rice-Tracey void growth model and the Gurson-Tvergaard-Needleman (GTN) model. ...
Numerical analysis of local and global buckling of a stiffened beam-column
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
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 ...
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 ...

Eksperimentalno analiziranje rasta prsline u pojedinim konstituentima zavarennh spojeva kompleksno legirannh čelika visoke čvrstoće na epruvetama i u realnim konstrukcijama, kao i uticaj rasta prsline na sigurnost zavarenog ...
Analysis of the supporting structure of composite material tool machine using the finite element method
(Univ Osijek, Tech Fac, Slavonski Brod, 2015)
Machines aimed for different purposes must be designed taking into account specific shape, type of load and materials they are made of. Nowadays different design solutions can easily be examined by using the finite element ...
Uticaj ispitivanja probnim pritiskom na nastanak i rast prslina u zavarenim spojevima opreme pod pritiskom / Probe testing effect on crack initiation and growth in pressureized equipment welded joints
(Univerzitet u Beogradu, Mašinski fakultet, 2018)
Predmet doktorske disertacije je analiza problema vezanih za inicijaciju i rast prslina u zavarenim spojevima opreme pod pritiskom tokom procesa ispitivanja pritiskom, kao i utvrđivanje matematičkih modela i procedura ...
Trodimenzionalna optička analiza deformacija polimerizacijske kontrakcije stomatoloških kompozitnih materijala na bazi smole / Three-dimensional optical strain analysis of polymerisation shrinkage of resin-based dental composite materials
(Univerzitet u Beogradu, Mašinski fakultet, 2012)
Svetlosno polimerizujući kompozitni materijali na bazi smole su na osnovu dobrih mehaničkih osobina, realtivno niske cene, jednostavne primene, pozitivnog odgovora na aktuelne estetske zahteve, postali materijal izbora za ...
Procena integriteta i veka zavarenog panela primenom lokalnih napona / Assessment of the integrity and life of welded panel using local stresses
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2022)
Relevantne lokalne karakteristike zamornog opterećenja su najveći amplitudni napon i odgovrajauća srednja vrednost napona, koje treba odrediti za celu komponentu. Relevantna svojtva materijala se onda upoređuju sa dobijenim ...
Experimental and numerical stress and strain analysis of the boiler reversing chamber tube plate
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
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 ...
Uticaj ispitivanja probnim pritiskom na nastanak i rast prslina u zavarenim spojevima opreme pod pritiskom
(Mašinski fakultet Univerziteta u Beogradu, 2018)
The applied stress level which will produce plastic deformations in WM is lower than the BM yield strength, not to mention effect of over-loading. One should also keep in mind that welded joints are places with non-uniform ...
