abaqus theory 3.6.8例子学习：复合材料。该例子详细介绍了如何在Abaqus中模拟复合材料层合板的力学行为，包括材料定义、单元选择和边界条件设置。通过对比实验数据与仿真结果，验证了模型的有效性。用户可参考此例掌握复合材料各向异性特性的建模方法，以及如何利用Abaqus的材料库和用户子程序扩展功能处理复杂复合材料体系。

这个简单算例实际在告诉我们abaqus是怎么计算transverse shear stiffness

This method, outlined below, provides an approximate method for calculating interlaminar shear stresses and supplies reasonable estimates of transverse shear stiffness. In this calculation Abaqus assumes that the shell section directions are the principal bending directions (bending about one principal direction does not require a restraining moment about the other direction). For composite shells with orthotropic layers that are not symmetric about the shell midsurface, the shell section directions may not be the principal bending directions. In such cases the transverse shear stiffness and interlaminar shear stresses are less accurate approximations and will change if different shell section directions are used.

   这个例子是所谓的principal bending directions简单情况，在主方向弯曲，不会出现其他方向的所谓“约束力矩”
