Stress concentration and crack nucleation at the end of a low-angle tilt boundary

Abstract

A low-angle tilt boundary (LATB) is easily sheared by dislocations identical to those constituting the boundary. This shear results in the creation of semi-infinite low-angle tilt boundaries, which generate a stress at their tips large enough to cause fracture.
