matlab有限元结构动力学分析实例，对结构动力学分析过程中的频率，特征值，模态的求解都有详细实例(Examples of finite element dynamics analysis of matlab, there are detailed examples for the frequency, eigenvalues, modal solutions in the process of structural dynamic analysis.)

These composite materials generally exhibit brittle damage behavior. The anisotropy in the material and different kinds of failure mechanisms make it difficult to accurately characterize the behavior of composite materials. The present work aims to
