Crushing analysis of splitting–bending steel plate energy absorber under axial loading

摘要: Abstract The splitting and bending behaviour of steel plates was used as energy absorber in our previous work. Two experiments with 9 mm were carried out. finite element models presented this study are based on experimental tests good agreement is achieved between the results. Through observation results numerical simulation, typical deformation process variations stress triaxiality elements presented. parametric performed using under quasi-static loading conditions. It found that plate thickness, die angle, width distance baffle have a distinct effect absorption. outcome full detailed design guidelines for such energy-absorbing structures. velocity investigated result shows dynamic similar to loading, steady state force increased impact increased. With bigger increase larger.
