MODELING OF PLASTIC ZONES IN THE PROCESS OF SHEAR DEFORMATION OF A HALF LAYER CONTAINING A CRACK

We study the evolution of plastic zones in a perfectly elastoplastic half layer containing a crack in its median plane under the conditions of antiplane deformation caused by displacements of the rigid faces of the half layer, deduce equations for the boundary of the continual plastic zone and its l...

Zusammenfassung:We study the evolution of plastic zones in a perfectly elastoplastic half layer containing a crack in its median plane under the conditions of antiplane deformation caused by displacements of the rigid faces of the half layer, deduce equations for the boundary of the continual plastic zone and its length in the plane of the crack as functions of the load, and perform the approximate analysis of the stress intensity factors of the elastic solution for the zones (the so-called linear model of the plastic zone).
