Abstract

Abstract: With the impact of environmental protection awareness and the accelerated energy crisis, automotive lightweight technology has been developed rapidly. However, it is necessary to ensure the passive safety performance of automobiles in the lightweight process. In this paper, the tensile tests under different strain rates, fracture tests and automotive safety component test are introduced in details on the basis of the dynamic strain response and large deformation characteristics of the automobile in collision process. The metallic alloy sheets are adopted and their dynamic response and fracture behavior are summarized from the aspects of mechanical properties and fracture performance. The establishment and application process of the fracture model of metal materials are fully presented in the paper and provides a reference for the establishment of accurate material model in the field of vehicle collision safety. Taking the press forming material which has been widely used in safety components as an example, the mechanical properties of the material in different states are obtained through the above-mentioned tests. Through data processing and simulation analysis, the dynamic material fracture model is established and used in the failure simulation of actual parts. The result indicate the mode is practical and can accurately predict the fracture behavior of parts.

Key words: dynamic deformation, material mechanics, constitutive mode, fracture mode
