Abstrak Crash box is part of the supportingcomponents on vehicle safety, especially cars. The crash boxis designed to reduce the occurrence of driver’s injuries due to collisions. This study aimed to determine the capability of energy absorption and deformation patterns in the crash box using a three-segment circle cross-section. The research method was quasi-experimental with a simulation using Finite Element Method software. The crash box simulation carried out with a 200 kg impactor on a speed of 7.67 m/s. The independent variable in this study is the material exposure variation in the crash box using steel-aluminum-steel and aluminum-steel-aluminum. The dependent variables were energy absorption, force reaction and deformation patterns occurring in the crash box. Based on the simulation results, the values ofenergy absorption was 82452 J and force reaction was 1127700 N in the crash box of steel-aluminum-steel material. Meanwhile, the crash box material of aluminum-steel-aluminum has an energy absorption value of 236210 N, force reaction of 12432 J and a better and more stable on deformation pattern.
