Abstract
Dislocation emission induced by a crack tip is probably the most important unsolved physical problem of the theory of dislocations. This problem is addressed in the Chapter using the approach named by John Gilman the nanofracture mechanics. To simplify mathematics and focus on the physical aspects of the problem, we study: (i) small deformations of a single cubic crystal (or nanoscale strains of a grain in a polycrystalline material), and (ii) small scale yielding caused by screw or edge dislocations which are collinear to the rectilinear crack front (plane model, that is, plane strain or plane stress or plane shear).
