Structural integrity analysis of a cracked pressure vessel
(Institut za ispitivanje materijala, Beograd, 2021)
Stress distribution, as obtained by finite element method (FEM), and corresponding fracture mechanics parameters, have been used for the integrity assessment of a pressure vessel. Once the stress distribution is known, the ...
Analysis of the Influence of Microstructure Heterogeneity and Mechanical Properties of Welded Joint Constituents on Fracture Toughness for Plane Strain, K-Ic
(Trans Tech Publications Ltd, Durnten-Zurich, 2012)
The problem of fracture toughness, K-Ic, determination at a crack tip localized in a welded joint is placed in principle because fracture mechanics assumes homogenous material, not only around the crack tip but on a distance ...
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 ...
The influence of the temperature and exploitation time on the behaviour of a welded joint subjected to variable and impact load
(International Conference on New Trends in Fatigue and Fracture, 2018)
This paper presents the analysis of the temperature and exploitation time influence on the resistant measure to brittle fracture of welded joint constituents of the new and exploited low-alloyed Cr-Mo steel A-387 Gr. B ...
Repair Welding Of Lower Rails Of A 30CrMoV9 Steel Transport Beam And The Conditions Under Which The Welding Procedure Must Be Carried Out
(Proceedings of the 5th International Scientific Conference on Advances in Mechanical Engineering (ISCAME 2017), 2017)
Welding technology used for repairing of the lower rail of a 30CrMoV9 steel transport beam is
presented in this paper. Following the previously performed repair welding, a large number of
cracks were detected, located ...
Experimental j-integral Determination of Different Weldments Region at Low Temperature
(Proceedings of the 2nd International Scientific Conference on Advances in Mechanical Engineering (ISCAME 2014), 2014)
Behavior of welded joint regions (parent material, weld metal and heat-affected zone) in the presence of crack is presented. Specimens were made of high-strength low-alloy steel and were tested at -40°C. Diagrams load ...
