Simpson 求解积分，很方便使用的求解积分的方法。希望大家喜欢(Simpson for integration, it is easy to use solution of the integral approach. I hope you like)

层合板的刚度的计算和验算，包括拉伸刚度A、弯曲刚度D以及耦合刚度B。 首先要给定层合板的各个参数，具体有：层合板的层数N；各单层的弹性常数E1、E2、 、G12；各单层对应的厚度；各单层对应的主方向夹角 。(The stiffness of laminated plates is calculated and checked, including tensile stiffness, A, flexural stiffness, D and coupling stiffness B. First of all, it is necessary to give the parameters of laminated plates, such as the number of plies N, the elastic constants of each layer, E1, E2, and G12, the thickness of each monolayer, and the angle of the main direction corresponding to each single layer.)

说明：  calculate wear the subroutine coded by Fortran and can be used for the 2D model and useful for the wear calculation
