A CRACK WITH INTERFACIAL BONDS BETWEEN FACE ON BORDER OF THE UNIT OF THE ROAD COVERING AND THE ELASTIC BASIS

Abstract

The plane problem about the crack - stratification, arising on border of the unit of the road covering linked to the elastic basis from other elastic material when normal loading is enclosed to a surface of a covering is investigated. 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.
