平面应力状态下J积分与K_Ⅰ关系的推导

The derivation of relationship between J integral and K_Ⅰ in view of the plane stress state

在文献[1,2]的平面应变状态下J积分与应力强度因子KⅠ关系推导的基础上,详细地推导了平面应力状态下J积分与应力强度因子KⅠ的关系,这方面推导具有重要的理论价值与参考意义.

The author deduced the relationship between J Integral and Stress Intensity Factor KI in view of the plane stress state in detail ,which was based on the documentary[1][2]＇s derivation of relationship between J Integral and Stress Intensity Factor KI in view of the plane strain state. Therefore, this derivation was with important theory value and referred meaning.
