有限元法模拟混合物的冲击压缩特性

SIMULATION OF SHOCK COMPRESSION BEHAVIOR OF MIXTURE BY USING THE FINITE ELEMENT METHOD

将混合物作为组元颗粒在空间的随机排列，采用三维动力有限元程序模拟其冲击压缩特性。给出了以铜和铝两种金属单质组成的混合物算例，与用“叠加原理”计算的结果作了比较。

In this paper,the shock compression behavior of mixture is simulated by using a threedimensional finite element code.The mixture is as a randomly distributed component grains in space.As an example,the mixture composed of copper and aluminum is calculated and the result is compared with the “superposition principle”.They are in accord with each other.
