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.

โฆ Synopsis
In a linear elastic analysis of mixed mode fracture problem, a general G-K relation has been obtained based upon the maximum energy release rate criterion. The expression of nonlinear energy release rate for specimen with an arbitrarily oriented crack subjected to biaxial loading has been formulated. The numerical results which indicate the biaxial effect are presented.

## Several theories have been proposed for the failure of metals, as well as for the angle of crack propagation in mixed mode loading. In order to demonstrate the validity of these theories, the majority of tests have been carried out with an oblique crack placed in a uniaxial stress field. Better
Fracture tests of aluminum/epoxy dissimilar materials with an interface crack are carried out under comprehensive mixed mode conditions, using circular disk type (brazil-nut-sandwich) specimens under compression or tension loading in various directions. The stress intensity factors for an interface

A prediction of the direction of incipient crack growth in brittle-like materials and the associated fracture loci under mixed mode loading is proposed. It is postulated that the direction of unstable crack propagation is determined by the "weakest" near-tip element defined as the one which would re
A new hypothesis is presented for dete~ining the mixed-mode fracture toughness criterion of brittle materials such as rocks, cement and ceramics. The obtained criterion gives a reasonable result, which is in good agreement with published data. The data, obtained here for mixed-mode fracture toughnes
