| 摘要: |
| 元胞法(Method of Cell)是在有效刚度理论的基础上发展起来的新方法，可以用来构造具有周期性结构单元的材料的本构，也可以用来模拟应力波在材料中的传播问题，尤其是具有分层结构的材料。本文中给出两种常见的初值条件，并利用该方法模拟了非线性弹性材料的动态响应，研究了波在该层合材料中的振荡现象。 |

| Abstract: |
| The method of cell, based upon the effective stiffness theory, can be applied to construct the constitutive equations of materials with periodical structure, especially laminated materials, and simulate the propagation of stress wave. In this paper, two kinds of initial conditions are listed for the simulation of dynamic response of nonlinear elastic materials according to this method, and the oscillations of stress wave in laminated materials are researched. |
| Keywords: method of cell stress wave dynamic response nonlinear elasticity |
