development of the model of Atkinson and Kay is presented, in which time-dependent plastic relaxation at a crack tip is represented by the movement of a single dislocation with a variable Burgers vector. The predictions of the model are compared with observations of crack opening displacement in mil
The problem of the equilibrium of a plane with a circular hole and a shear crack is considered to model failure of an excavation (borehole or circular opening) in rocks weakened by discontinuities (planes of weakness). It is assumed that sliding occurs in a part of the plane of weakness when the Moh
