复合材料力学上机编程作业(计算层合板刚度)(共10页)

1、第 页复合材料(f h ci lio)力学上机编程作业学院(xuyun)：School of Civil Engineering 专业(zhuny)：Engineering Mechanics小组成员信息：James Wilson（2012031890015）、Tau Young（2012031890011） 复合材料力学学了五个星期，这是这门课的第一次编程作业。我和杨涛结成一个小组，我用的是Fortran编制的程序，Tau Young用的是matlab编制。其中的算例以我的Fortran计算结果为准。Matlab作为可视化界面有其独到之处，在附录2中将会有所展示。 作业的内容是层合板的刚度的

2、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。然后就要计算每个单层板的二维刚度矩阵Q，具体公式如下：；得到Q矩阵后，根据课本上讲到的得到。 然后根据z坐标的定义求出到，接下来，最重要的一步，根据下式计算A、B、D。一、书上P110的几个问题可以归纳为以下几个类型。（1）正交铺设5层对称层合板（T5-7）数据文档层数5 层序数厚度mE1（Pa）E2（Pa）v12v21G12（Pa）角度（）1 1.00E-039.60E+102.40E+100.10 0.40
