Fracture behavior of reactor steel 20MnMoNi 55 in the transition temperature region
(Elsevier B.V., 2021)
The fracture represents the final phase of crack propagation, and the causes of their occurrence or partial crack propagation in the real constructions made of ferritic steels can be different. Along with cracks, influences ...
Increased hydraulic resistance in tubes of once-through boiler due to fouling: a case study of 650 MWe ligite fired unit
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), 2022)
The analysis of pressure changes in water and steam flow along the entire once-through steam
boiler tube system at the 650 MWe lignite fired Unit was carried out after the long operational period
of almost 30 years ...
Numerical simulation of crack growth in a welded joint with defects
(Elsevier B.V., 2021)
Research presented in this paper involves the numerical simulation of crack growth in a welded joint made of common structural steel S235JR2, but with the presence of a number of different welding defects, which represents ...
Gasification of wastes and residues for electricity production
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2021)
Gasification technology presents one of the promising options for converting biomass energy into electricity. Gasification process converts carbonaceous materials into carbon-monoxide, hydrogen, carbon-dioxide, and gaseous ...

(Springer Science and Business Media Deutschland GmbH, 2022)
This paper investigates the supply (access to finance) and demand (innovation-driven SMEs and talent communities) perspectives in the Danube macro-region (DMR). The purpose of this the empirical analysis is to identify ...
Analysis of fatigue behaviour of a bridge welded structure
(Elsevier Science Bv, Amsterdam, 2022)
Results of extensive experiments involving the fatigue behaviour of welded structures which are a part of the "Gazela" bridge in Belgrade, Serbia, are presented in this paper. After non-destructive testing of these structures, ...
Stress Corrosion Crack Growth Simulation by the Finite Element Method
(Springer Science and Business Media Deutschland GmbH, 2022)
Stress corrosion crack growth in mild steel was investigated by using the finite element simulation method. A model simulating crack growth considered an edge crack located on the metal surface, under tensile remote stress ...
