Numerical simulation of crack growth in welded joints in the presence of multiple defects
(The 27th International Conference on Fracture and Structural Integrity, 2023)
Simulation of crack initiation and propagation which occurred during the tensile
testing of real welded joint specimens made of low-alloyed low-carbon structural
steels is presented in this paper. Welded joints in questions ...
Application of numerical methods in design and analysis of heart valve prostheses mechanical behaviour
(2015)
In this paper the analysis of existing design of mechanical heart valves is presented, as well as the
application of advanced numerical methods, primarily the finite element method for the design and analysis of these ...
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 ...
Crack Growth Rate Analysis of Stress Corrosion Cracking
(Univ Osijek, Tech Fac, Slavonski Brod, 2021)
A theoretical film rupture model was used for computational procedure to predict the crack growth rate within the Stress Corrosion Cracking (SCC) conditions. Chemical, electrochemical and mechanical aspects of the SCC were ...
Numerical and experimental determination of stress concentration factor for a pipe branch model
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
The subject of this paper is testing of complex geometrical structures, i.e. stress analysis of a pipe branch model of A6 third pipeline at Hydropower Plant Perucica, Niksic. Analysis of pipe branch model stress distribution ...
Experimental and numerical investigation of Ti-6Al-4V alloy behaviour under different exploitation conditions
(Society for Structural Integrity and LifeIMS Institute, 2022)
The paper involves experimental testing of titanium alloy Ti-6Al-4V specimens, based on which numerical models are made to provide the basis for further investigation. Due to the exploitation conditions these implants are ...
Spur gear model for prediction of fatigue damage initiation in contact zone
(International Journal of Powertrains – „Special Issue on Technologies and Models for High Power Density Geared Powertrains", 2016)
The objective of this paper is to give a new viewpoint in contact fatigue assessment in the spur gears. The presented research is based on up-to-date methods and multidisciplinary approach, and enables direct prediction ...
