Abstract :Crash boxes are fasteners that are used in automobiles and have the ability to absorb energy emerged during impact. These parts can have different geometric properties. Within the scope of this study, corrugations of 1 mm, 3 mm, 5 mm in diameter were formed on the crash boxes. They are designed to have 0°, 2° and 4° taper angles. Each crash box has a wall thickness of 2 mm. The crash boxes designed were subjected to a velocity of 17 m/s with a mass deformation of 500 kg and crashing performances were investigated. As a result, the corrugation size was found to have influence on crashworthiness performance.
