摘要
用Williams幂级数展开的方法,对开裂Reissner板进行了特征展开,获得了Reissner板裂纹尖端位移、应力展开式,然后利用分区广义变分原理对Reissner有限板计算了裂端应力强度因子,结果令人满意。
On the basis of Williams series method, Reissuer Plate with a crack is unfolded, and the displacement and stress fields near the crack tip are obtained. The subregion seneraled variahonal Principle is used to solve the stress intensity factor of the finite Reissuer plate. The results are satisfactory.
