Abstract

Abstract: The author deduced the relationship between J Integral and Stress Intensity Factor K1 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 K1 in view of the plane strain state．Therefore，this derivation was with important theory value and referred meaning．

Key words: plane stress state, J integral, stress intensity factor, fracture mechanics

摘要： 在文献【1，2】的平面应变状态下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K1的关系，这方面推导具有重要的理论价值与参考意义．

关键词: 平面应力状态：积分, 应力强度因子, 断裂力学
