摘要 讨论了虚拟裂纹闭合法在工程软件中的实现策略,以MSC.Patran为平台,利用其强大的前后置后处理功能,使用PCL语言开发了二维和三维虚拟裂纹闭合法计算模块和用户图形界面,通过二维和三维算例验证了虚拟裂纹闭合法计算模块的正确性。 The implementation strategy for using the Virtual Crack Closure Method （VCCM） in engineering commercial programs is discussed. Then by making use of the Patran command language （PCL）,two dimensional and three dimensional VCCM algorithmic models together with graphical user interface （GUI） forms are developed in MSC. Patran software which is good at preprocessing and postprocessing. Comparison of the results with the reference solutions shows good agreement. Meanwhile the validity and accuracy of this models are substantiated.
