Abstract
Different high-strength structural steel materials such as DP590, TR590, DP780, QP980, DP980, and MS1180 are tested for frontal impact in this research. The deformation modes and energy absorption characteristics of various materials and thicknesses are studied based on the trolley bump test. Then the average acceleration and the light weight potential under each structure are analyzed and compared. The research providedan optimized direction for the choice of stringer material and thickness.
