character dimension, boundary integral equation, linear elasticity, ideally elasticplastic model

. Description of plastic deformation in the context of flow theory is a classic way of mechanics of continua. But a solution of the problems is found in the context of a hard plastic model when it’s ignored elastic deformation as compared with plastic. Target connected elastoplastic settings mate vagueness of tensions and deformations for the field of plastic deformation. However in various cases this problem is avoid. In the article is investigated the important problem of mechanics of destruction which consists of modeling of behavior plastic thin zone depending on the view of plane problem. In the classic way [7,11] thin plastic zone associate with an influence of cohesion force of constant activity, which don’t connect with change from elastic to plastic condition. In the article plastic field is applied to deformable solid and its condition is rote in the context of the expression mechanics of continua. In the article – is obtained of principle difference tensity in the apex of a split from view plane problem.
