| 摘 要： | 为研究有界弹性圆盘内含有互不相交十字型裂纹的循环对称断裂问题,通过应用平面弹性复变方法将满足已知边界条件的弹性平衡问题转化为解析函数边值问题,把边值问题化为Cauchy核的奇异积分方程组,最后利用Gauss-Chebyshev数值计算方法求出此方程组的数值解,并给出了应力强度因子(SIF)的数值结果.

| Abstract: | The circular symmetric problem of bounded elastic disk with non-intersecting cross-crack is discussed.By using plane elasticity complex variable method,the mathematical model is established by boundary value problem of analytic functions.Furthermore,it can be changed into singular integral equations with Cauchy kernel.With Gauss-Chebyshev method,the numerical solutions of the equations and the stress intensity factors are obtained. |
