Description
Summary:We describe a method to tackle problems such as the presence of cracks or a region of partial slip, in wedge shaped domains, using distributed dislocations, alternatively considered as the edges of complete contacts. An asymptotic solution is sought, which is then applicable to many different contacts. Efficiencies are sought and described in comparison to previous approaches, both in terms of computational cost and kernel complexity. Three example problems, a crack, a slip zone, and a pair of cracks, are discussed.
