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 ener
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
The strain energy criterion for crack propagation proposed in the paper is based on the principle that the direction of crack propagation takes place along the direction where the distance from the crack tip to a certain contour line of constant distortional strain energy density is minimum, and the
