Dynamic axial crushing of square tubes
WebJan 15, 2024 · The collapse of tubes under axial load is an important subject from the safety point of view, particularly in the design of energy absorbing devices used in many engineering applications. In this study, quasi-static and dynamic experiments were carried out on square thin-walled aluminum extrusions to investigate the effects of circular holes. WebCrushing Behaviour of Square Steel Tubes Isaac C.W. a*, Oluwole O. b. Abstract — The dynamic axial crushing of a thin-walled hot-rolled carbon steel square tubes are performed and their results were compared with published numerical and experimental data of a thinwalled high-strength steel. The goal is to determine and compare the -
