摘要
充分利用MSC.Patran的可视化及分网功能,结合有限元重合网格法(S-FEM)在裂纹问题分析中的优势,以MSC.Patran为平台,使用PCL语言开发了求解裂纹问题的二维有限元重合网格法分析模块,应用此模块计算单边直裂纹和斜裂纹矩形板应力强度因子,并模拟了斜裂纹的裂纹扩展路径,验证了程序模块及方法的正确性。
By applying the visualization and mesh generation capability of MSG. Patran and taking advantage ot the S-version finite element method （S-FEM） in solving crack problems, a module for solving two dimensional crack problems based on s-version finite element method is developed using the PCL language on MSC. Patran platform. Then the stress intensity factors of rectangular panels with single-edged straight crack and oblique crack are calculated. The crack propagation path of oblique crack is simulated. Comparison of the results with those in References [ 7 ] and [ 8 ] shows good agreement.
