摘要
讨论了汽车碰撞数值计算中的应变率效应问题，分别将静态弹塑性理论和应变率有关理论中的 Ｓｙｍ ｏｎｄｓ模型引入材料的本构关系中，并用试验考证和分析了两种本构关系模型对计算结果的影响。
The problem of strain rate effect is discussed in this paper,which occurs in vehicle crash simulation.Two material models are discussed,which are elastic plastic hardening material law without and with strain rate(in particular symonds law is selected). Effect of two models on calculating results of numerical simulation of vehicle crash is also analyzed.
