摘要：
This paper describes a simple method of estimating J integral for biaxially stressed Mode I cracks. Finite element analyses were made to obtain the relationship between J integral and crack opening displacement by changing constitutive relation, crack length and stress/strain biaxiality. A simple method was proposed to estimate J integral based on the equivalent strain based on crack opening displacement for Mode I cracks under biaxial stress states.
