Abstract

A model for crack propagation along a non-locally pre-stressed interface in ceramic materials is studied. The problem is analysed on a discrete chain of oscillators, with local and non-local interactions. The pre-stressed state is defined by the stiffnesses of the non-local links. Small negative stiffnesses of such links reveals the existence of crack speeds supporting stable crack propagation, which is not possible in a structure which has only local interactions.
