Comparison of experimental, numerical and analytical risk assessment of oil drilling rig welded pipe based on fracture mechanics parameters
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Fracture mechanics parameters are used for experimental, numerical and analytical risk assessment of structural integrity and life of oil drilling rig welded pipe with a crack. As a simple analytical tool, the Failure ...
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 ...

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, ...
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 ...
