依据边界层理论分析的带圆孔对称复合材料层合板的应力解析解,开发相应的软件,计算铺层交界处的层间应力。进一步增加Hashin失效判据,得到层合板各个铺层不同失效形式下的区域分布。该软件是基于Matlab开发的,非常适用于带圆孔复合材料层合板结构打样阶段的分析。
The software for calculating the interlaminar stress components around a hole in symmetric composite laminates under inplane loading is programmed. Interlaminar stresses are obtained on basis of boundary-layer theory. Further, Hashin failure criterion is added to analyze failure regions around the hole. This software pmgrammed with Matlab is useful for analysing composite laminates subjected to in-plane loading with curved free edges in design phase.
