Model analysis of bucket wheel excavator SchRs 630 strength
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The possibilities of testing real constructions are often limited, especially in case of large constructions. The idea of model testing is to create a sub-scaled model in order to anticipate the behavior of the real ...
Editorial - Damage, cracks and failure analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The 1st Virtual European Conference on Fracture (VECF1) has gathered more than 300 researchers from all over the world. They have presented more 320 papers, including 9 plenary lectures in the scope of the main VECF1 topics. ...
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 ...
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 ...
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 ...
Recent Advances on Hydrogen Embrittlement Understanding and Future Research Framework, Editorial
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
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 ...
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 ...
Determination of the Actual Stress-Strain Diagram for Undermatching Welded Joint Using DIC and FEM
(MDPI, Basel, 2021)
This paper presents new methodology for determining the actual stress-strain diagram based on analytical equations, in combination with numerical and experimental data. The first step was to use the 3D digital image ...
