The Stability

In a previous paper the interaction between two coplanar dislocation-type cracks was studied, the crack openings being described by continuous distributions of dislocations. A similar approach is used here to examine the stability of an infinite periodic sequence of coplanar dislocation-type cracks, each dislocation being such that its associated extra material is pointing in the same direction. Primary consideration is given to the criterion for the cracks to join up thereby causing complete fracture of the solid, and the characteristics of the model are applied to a very brief discussion of some experimental results on the deformation of magnesium oxide single crystals.
