Plane-strain deformations of an isotropic and homogeneous Hookean body containing a crack are studied and it is required that the dilatation everywhere in the body be. greater than or equal to a constant. Following Prager, the region where the dilatation always equals the constant is identified as t
Plane strain deformations near the tip of a crack between two homogeneous and isotropic linear elastic bodies are studied on the assumptions that the two surfaces on either side of the crack contact each other and that the dilatation everywhere in the body is greater than or equal to a constant. The
The characteristics of the plastic enclave at the tip of a crack in a medium subjected to stress are investigated by means of a dislocation model. A model in which dislocations can glide along a plane coplanar with the crack has previously been given by Bilby, CottreU and Swinden (1), and it is the
Ah&act-The asymptotic form of the stress and displacement components near the tip of a straight crack in a generally rectilinear anisotropic plane elastic body are resolved. As in the isotropic analysis, the solutions for the stresses display a r -i'\* dependence, where r is the distance from the ti
