✦ Synopsis

The fracture criterion of mixed mode crack has been investigated extensively by many people on the basis of Griffith's theory. In this paper, the energy release rate of crack propagation along an arbitrary direction is obtained by the use of Griffith's theory. Then the general expression of the energy release rate criterion has been derived. The results have been compared

with the measured data of the fracture testing under combined Mode II-III and Mode I-II-III loading.

As can be proved from theoretical analysis, some mixed mode fracture criteria may be converted into an elliptical or ellipsoidal formula with the aid of mathematical translation. Others are of themselves an elliptical or ellipsoidal formula. Hence, on the basis of Griffith-Irwin theory, the paper su

Griffith's criterion for crack propagation is generalized to consider penny-shaped cracks in a spatially uniform, but otherwise arbitrary, state of stress.

Furthermore, we have proved that the null space of the linear operator of Piola-Kirchhoff stress history functional is the direct sum of the null space of linear operators for 6-D vector subspace N, and N,. Here we can naturally classify the fracture of isotropic material with memory into two types.
