Life cycle assessment of wood chips supply chain in Serbia
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Two most common systems of forest biomass supply chains in Serbia are evaluated by using the Life Cycle Assessment (LCA) approach: 'cut-to-length' system with penduculate oak (CLO) on flat terrains with a tractor equipage, ...
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 ...
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 ...
Structural integrity and life assessment of rotating equipment
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Failures of rotating equipment often cause severe consequences, so it is necessary to study their integrity and life as detailed as possible, especially when crack is detected. In the case studied here, hydro power plant ...
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 ...
Thermal-hydraulics of helium cooled First Wall channels and scoping investigations on performance improvement by application of ribs and mixing devices
(Elsevier Science Sa, Lausanne, 2016)
The first wall (FW) of DEMO is a component with high thermal loads. The cooling of the FW has to comply with the material's upper and lower temperature limits and requirements from stress assessment, like low temperature ...
Influence of welded joint microstructures on fatigue behaviour of specimens with a notch in the heat affected zone
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this paper, the results of determining the Paris law coefficients, C and m, are presented, based on the experimental data obtained by three-point bending testing of 8 welded joint specimens. The specimens were taken ...
Fracture mechanics and fatigue crack propagation in armor steel welds
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The welding process of armor steel is a complex process due to possible welding faults appearing in all zones of weld metal joint in the form of cracks and pores, as results of high percentage of carbon in the base metal. ...
