Interactions of Four Edge Dislocations with Crack

Abstract

The stress field is determined in an infinite nonlocal elastic solid weakened by a Griffith crack and four edge dislocations. Dislocations are located symmetrically with respect to the crack which is subject to a uniform tensile field. The problem is considered to be a plane strain problem in nonlocal elasticity. Keywords: Mathematical models, Elastic solids, Griffith crack, Edge dislocations, Tensile fields, Plane strain, Crack problems.
