摘要
本文使用边界积分方程方法研究了三维无限弹性体中含有一个受非对称载荷作用的外部圆形平片裂纹的轴对称问题,获得了裂纹面的位错和应力强度因子的精确解.
The axisymmetric problem of an external circular crack in a threedi-mensional infinite elastic body and under the unsymmetric loads is investi-gated by using the boundary integral equation method.The dislocations ofcrack surfaces and the exact solutions of stress intensity factors are obta-in ed.
