Numerical and Experimental Investigations of Fracture Behaviour of Welded Joints with Multiple Defects
(MDPI, Basel, 2021)
Current standards related to welded joint defects (EN ISO 5817) only consider individual cases (i.e., single defect in a welded joint). The question remains about the behaviour of a welded joint in the simultaneous presence ...
Integration of solar energy by nature-inspired optimization in the context of circular economy
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The purpose of this paper is to make a research on solar power plants integration in an electric power system, taking into account all costs arising from circular economy criteria. Four scenarios of solar power plant ...
Faktori sigurnosti u proračunu debljine zida kolona za rektifikaciju / Safety factors in wall thickness calculation of rectification columns
(Vojnotehnički institut, Beograd, 2021)
Kolone za rektifikaciju gasa veoma su važan deo svake fabrike. Njihovi iznenadni otkazi svakodnevno uzrokuju ogromne gubitke, dok curenje tečnosti može biti veoma opasno po ljude i životnu sredinu. Iz tog razloga, pravilan ...
Fatigue crack growth in a structure exposed to high temperature
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The exhaust nozzle, made of titanium, is the part of a jet engine where the final expansion of the hot gas from the turbine occurs and where the speed of the exhaust gas is further increased to create thrust. During the ...

(Pergamon-Elsevier Science Ltd, Oxford, 2021)
This paper involves the analytical and numerical calculations of the the largest pre-stressed concrete free-standing structure in the world - the Dome of the "Hall 1 of the Belgrade Fair", designed by a well-known Serbian ...
Structural integrity assessment of welded bucket-wheel boom
(Institut za ispitivanje materijala, Beograd, 2021)
Research is conducted on the causes of damage and the structural integrity assessment of the bucket-wheel boom welded lattice structures, before and after the repair of vital structures. Additionally, the paper describes ...
Welded joint geometry effect on fatigue crack growth resistance in different metallic materials
(Elsevier Sci Ltd, Oxford, 2021)
Fatigue crack growth through different welded joint regions was investigated, in terms of welded joint geometry and fatigue crack position. In the first phase of investigation, numerical simulation of crack growth in a ...
Human factor risk management procedures applied in the case of open pit mine
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
Risk management aims to provide a controlled work environment to ensure the safe operation of the high-risk systems. It is a dynamic process which work in a continual state of change. The issue of human factor risk and ...
