Protecting a car in a low-speed collision is an essential for passenger safety. A box-shaped bumper beams were common and served as shock absorbers in a potential crash. In this simulation study, their comparative deformation and failure analysis of hollow and solid bumper beam is investigated. In this study, Aluminium 6061 T4 is used for the analysis. The crash phenomenon is simulated in which the vehicle hits a deformable concrete wall at a specified speed. Modeling of solid and hollow car bumper is approximated from Honda Civic car’s width and design. The bumper beam, actuating tubes and the retention plates supporting the beam and the concrete wall are modeled as deformable bodies. The crash event is simulated using the elastic–plastic finite element model through Von Mises yield criteria and isotropic hardening rule. The deformation behaviour and ductile failure of the solid and hollow bumper is predicted in the form of plastic strain localization in this study and compared.
