| 摘 要： | 介绍了元胞法，利用该方法模拟了材料弹性动态响应问题，并与传播矩阵方法的结果进行了比较。该方法易于程序实现，能很好地处理材料的层界面，协调计算精度与计算量之间的矛盾，比传统的差分法和有限元法减少了计算量。

| Abstract: | MOC(method of cell)is a new means of investigating the problem of wave propagation in materials with complex interior unit structure.The MOC can be used to investigate transient waves due to pulse loading as well as harmonic waves.MOC was introduced,then,it was used to simulate the problem of material dynamic responses in order to review the reliability of MOC.Comparison was made between the results obtained from this method and those from propagation matrix technique.The results from MOC are of high accuracy and MOC is easier to program than traditional difference method and finite element method. |
