Application of Explicit Finite Element Technology to Numerical Simulation of Body Thin-walled Structure

This paper used a computer numerical simulation method to study the crashworthiness of thin-walled structure,which is a typical energy absorbing structure in collision.The basic theory of explicit finite element method was introduced,two key technologies of simulation were presented,and the simulation of spot-weld was discussed.The model, validated by experiments,can be used for the further analysis of the crashworthiness of thin-walled beams.
