Abatraet-The new failure criterion of rock in plastic strain space is presented upon previous experiment results and the hypothesis that dissipation energy in a material causes failure. The main characteristics and applications to rocks of the criterion are discussed. The criterion can well explain

The elastic wave velocities in rock are reduced significantly by the presence. of microcracks. As a result of the stress history of the rock these microcracks frequently exhibit some degree of alignment. The rock therefore displays an elastic anisotropy determined by the shape and content of the cra
