성형효과를 고려한 차량의 정면충돌해석

This paper is concerned with a frontal crash analysis of a vehicle considering forming effects. The properties of formed vehicle structures have been changed by such as work-hardening, non-uniform thickness distribution resulted from the forming process. In this paper, the forming effects of the front side member assembly of a vehicle are considered. The plastic strain and thickness distribution from the simulation results of the forming process have been used as an initial condition for crash analysis.
