Influence of temperature and exploitation period on the behaviour of a welded joint subjected to impact loading
(Institut za ispitivanje materijala, Beograd, 2016)
Presented in this paper is the analysis of the influence of temperature and exploitation period on the measure of fracture resistance of welded joint constituents in both new and exploited low-alloyed Cr-Mo steel A-387 Gr. ...
Numerical analysis of different weld geometries of lap welded joint in ammonia transport tanks
(Institut za ispitivanje materijala, Beograd, 2017)
Presented is a comparison of stress and strain distribution in lap welded joints of different geometries, which are part of a pressure vessel used as an ammonia transport tank. For this purpose, two numerical models are ...
Izazovi budućih istraživanja u oblasti industrijske bezbednosti / Challenges of future research in the area of industrial safety
(Institut za ispitivanje materijala, Beograd, 2015)

Effect of locally damaged elbow segments on the integrity and reliability of the heating system
(Institut za ispitivanje materijala, Beograd, 2016)
This paper presents the integrity and reliability evaluation of the heating system as a whole, based on results of metallographic tests performed on parent material and the ultrasonic measurement of wall thickness of elbows ...
Stress state around imperfections in welded joints
(Institut za ispitivanje materijala, Beograd, 2015)
Because of their geometry, welded joints can cause a local increase of stress. In the presence of imperfections in welded joints the local stress additionally increases and can lead to the formation of cracks. Cracks are ...
