A Numerical Method for EnergyAbsorbing Structures under Crash

采用虚拟接触载荷法研究弹塑性大变形的接触问题，提出了接触分析的计算程序，对碰撞吸能装置中常见的一种薄壳结构作了比较详细的数值计算。研究结果表明该计算方法原理简单，有较高的精度、收敛性和效率。

The virtual contact loading method is adopted to study the elastoplastic contact problems with large deformation. The detailed computational procedure for contact analysis is proposed. The thinshell structure wildly applied in energy absorbing devices is calculated in more detail. It is shown that this method is simple and has higher accuracy, convergence rate and efficiency.
