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 ...
Laser Processing of Ni-Based Superalloy Surfaces Susceptible to Stress Concentration
(MDPI, Basel, 2021)
Reliable and resilient constructions are basic for ensuring the safety of various structures. The superalloys are used as constructive materials due to their superb mechanical properties and endurance. However, even these ...
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 ...
Recent Advances on Hydrogen Embrittlement Understanding and Future Research Framework, Editorial
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
Numerical simulation of "Hall 1 of the Belgrade Fair"
(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 ...
Effect of laser shock peening with and without protective coating on the microstructure and mechanical properties of Ti-alloy
(Elsevier Sci Ltd, Oxford, 2020)
Owing to their good mechanical properties, titanium based alloys are used for machine parts and devices that operate in demanding regimes and environmental conditions. Laser shock peening (LSP) is an innovative technique ...
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 ...
Stress intensity factors numerical calculations for two penny shaped cracks in the elastic solid
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
In the face of enormous costs of developing new aircraft, high fuel prices, increasingly demanding environmental standards, harsh economic race and the fight against competing manufacturers, today's aviation is adapting ...
Engineering critical assessment of steel shell structure elements welded joints under high cycle fatigue
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Existing flaws in critical parts of structural elements may lead to failures of subassemblies and, in case of lack of redundancy, even to the entire structure collapse. Considering the case of cyclic loading - wind load ...
Tie-rods of the bucket wheel excavator slewing superstructure: A study of the eye plate stress state
(Elsevier Sci Ltd, Oxford, 2020)
Tie-rods of the bucket wheel and counterweight booms are vital parts of the bucket wheel excavator slewing superstructure. This paper is dedicated to the problem of identifying the stress state of the critical cross-section ...
