Abstract
A simple anisotropic dislocation theory of the plastic zone near a nonsymmetric wedge-shaped crack is developed. The zone is described by some superdislocations with multiple Burgers vectors. The main parameters of the equilibrium zone (the strength and spread of the relaxation shears) are determined. Simple expressions for a symmetrical quasi-brittle crack are derived both, in anisotropic and isotropic elasticity. Capabilities of the theory developed to describe the interaction of different shear-type planar defects are discussed. The critical pressure is calculated necessary for crack plastic closing as well as the parameters of cracks arising during deformation under pressure. [Russian Text Ignored.]
