On the Energy Absorption Capability of Metallic Tubes Subjected to the Radial Wall Crushing Process

Metallic tubes, under axial loading, are frequently preferred in many different industries due to their high energy absorption efficiency. The studies increase the capacity (EAC) of these structures still up date. In this study, deformation behavior and EAC regionally pre-deformed identical aluminum steel tubes loading were investigated experimentally. Regional strength was obtained by radial wall crushing (RWC) process. RWC process is carried out radially desired areas metallic tube from outside with aid a specially designed device. Strengthening (hardening) occurs regions as result, can be increased. It also noteworthy that absorbed provided without reinforcement materials. When experimental results examined, it seen increased value approximately 23% 33%, respectively. addition increases, folding beginning directed using
