Axial crushing analysis of empty and foam-filled brass bitubular cylinder tubes

摘要: Abstract To reduce loss from collision, energy absorbers are used which dissipate upon deformation and folding in order to prevent damage critical parts of a structure. In this study, the empty polyurethane foam-filled bitubular tubes made brass with circular section were subjected quasi-static axial compression loading. Nonlinear dynamic finite element analyses carried out investigate details concerning crushing process by using explicit code ABAQUS. Satisfactory agreements achieved between experimental results. The validated model was then for parametric studies, determine effect filler tube geometry parameters (i.e. wall thickness, semi-apical angle) loading impact mass, velocity) on Dynamic Amplification Factor. results highlight advantages as absorber.
