Title:
DEVELOPMENT OF A CRACK WITH BONDS BETWEEN THE FACES IN THE PLANE UNDER NON-UNIFORM STRESS FIELD
Keywords:
isotropic plane in a non-uniform stress field, rectilinear crack with end zones, cohesive
forces.
Abstracts:
A homogeneous isotropic plane weakened by rectilinear crack with end zones with
bonds between the faces is considered. The model of crack with end zones, in which cohesive forces
of the material are act, is used. At the loading of the plane by non-uniform stress field in the end
zones the pre-fracture zones will occur, which are modeled as a zone of weakened interparticle
bonds of the material. The fracture process zone is a layer of finite length considering as a part of
the crack, in which bonds between the individual structural elements of the material is partially
broken. The problem of equilibrium of the plane with the crack with bonds between the faces in
the end zones under the influence of non-uniform stress field and tractions in the bonds, preventing
of crack disclosure is reduced to a system of singular integral-differential equations with Cauchy
kernel. From the solution of this system of equations the normal and tangential forces in the bonds
are found.
