Abstract
Recently the compatibility of crash safety and lightweight is one of the most important technical subjects in body design. It is considered that the resistant strength has to reach a balanced level between the energy absorption structures and the deformation control structures for crash safety design. Although the CAE technology has been widely and successfully used to get the characteristic values in the crash safety evaluation, it is necessary to accurately estimate the energy absorption of the structural member of car in the initial stage of the design for time saving. This paper analytically refer to the energy absorption of the axial compressions given at the collision.
