The problem on equilibrium of a crack on border of connection of materials at action of external normal loadings and tractions in the bonds interfering its disclosing, is reduced to system nonlinear singular the integro-differential equations with a nucleus such as Cauchy. The condition of limit equilibrium of a crack with a tip zones is formulated, taking account in view of criterion of limit traction of the bonds.road coveringcrackelastic basecriterion of limit traction of the bondsintegro-differential equationsдорожное покрытиетрещинаупругое основаниекусочно-квадратичная аппроксимациямеханика разрушения
