When a high level isotropicstress field is disturbed by a drilled hole, a relation of relieved strain vs. residual stress is derived by the basic equations of elastoplastic theory.
本文根据弹塑性理论基本方程，导出了高水平均匀残余应力场由于钻孔引起的松弛应变与残余应力的关系公式。

The stress intensity factors of both orthotropic and isotropic materials can be obtained from the present results.
正交各向异性和各向同性材料的应力强度因子均为本文的特例。

Description is given for a complex variable-variational method to investigate the stress intensity factors in anisotropic and isotropic plates with edge cracks subject to pin loads.
