摘　　要：采用PCL编程语言,在MSC.Patran平台下开发了一个针对复合材料层压板连接问题的二维强度校核软件.该软件既可以采用广义强度准则进行力失效判别,也可以采用特征线方法,结合Tsai-Hill准则、Hoffman准则、Tsai-Wu准则和Yamada-Sun准则对复合材料铺层进行应力失效判别.该软件还能够同时兼容MSC.Nastran和MSC.Marc的计算结果,将应力分析、失效判别、结果显示3个模块融为一体.通过显示失效区图形的方法,不仅可以表示强度校核结果,还为主要失效模式的推断提供参考依据.In this article,programmed by PCL,a 2D strength checking software for composite laminate based on MSC.Patran platform is developed.In the software,generalized strength criterion can be applied in failure judging by force components,as well as Tsai-Hill,Hoffman,Tsai-Wu,Yamada-Sun criterion with characterized curve method for each ply by stress components.Result files from both calculators,MSC.Nastran and MSC.Marc,are able to be attached.The functions of stress analysis,failure judging,and result requirement are combined in the software.Through displaying failure region,strength checking results can be acquired and reference for main failure mode can be supplied.
