| Abstract |
The method allowing one to separate singular components of the linear
elastic solutions at the corner points of solids was developed earlier for
the wedge-shaped punches [1] and cracks [2] and generalized to arbitrary
polyhedral angles [3]. In the present paper, this method is applied to
study the stress singularities in the neighborhood of corner points of the
front of the crack on the plane interface between two different materials.
The method is based on the reduction of standard three-dimensional boundary
value problems to spectral problems for one-dimensional integral operator by
using the Mellin transform. In the framework of this approach, we derive the
form of this integral operator for the problem under consideration,
implement the method on a computer, and perform the numerical
analysis of singular expansion characteristics as functions of the crack
aperture and the ratio of elastic characteristics of the materials. |
