VUMAT子程序，采用改进的Hashin准则计算三维复合材料失效-VUMAT subroutine with modified Hashion for 3D

一本有关复合材料的外文书，介绍了一些实例，也有三维正交hashin失效准则的vumat子程序，希望能对你有所帮助。(A foreign language book on composite materials is introduced, some examples, and a VUMAT subroutine with three dimensional orthogonal Hashin failure criteria, which I hope will help you.)
