The stress-strain state in a crystalline solid body is determined by solving the problem of the theory of elasticity for an edge dislocation containing a cavity on its continuation. The cavity is modeled by a microcrack. We deduce equations for the energy of a body containing a microcrack of this kind under pressure. The geometric parameters of the crack-like dislocation cavity and the lengths of equilibrium and nonequilibrium cracks are presented. We also determine the critical pressure corresponding to the onset of crack growth on the continuation of the dislocation defect. In addition, we computed the stress intensity factors for the indicated kind of cracks. [ABSTRACT FROM AUTHOR]
