摘要:
在裂纹问题超奇异积分方程方法的程序实现方面,如何获得比较快捷的运算速度是首先应当考虑的问题.以双材料平面中圆弧裂纹问题的程序设计为例,阐述数值积分方法、方程组求解方法、以及应力强度因子的精度控制等关键问题,并给出相应Fortran9.0例程.程序的实际运行效果表明,所采用的方法可以获得尽可能快捷而满足精度要求的计算结果.
Abstract:
As for hyper-singular integral equation methods procedures in the crack problem，how to get a fastcomputing speed is the first thing that must be considered. This paper deals with the programming on the arecrack in the plane bi-material , sets forth the numerical integration method，the method solving equations，theaccuracy control of the stress intensity factors，etc. and the corresponding Fortran routines are given. The re-sults of actual program running shows that the methods can get the result quickly enough and meet the require-ments of the calculation accuracy.
