Concentration of stresses near a debonded flexible inclusion in plane elasticity

Abstract

We study the concentration of elastic stresses around a debonded inclusion. The integro-differerential equations are obtained by using discontinuous solutions. The latter may be obtained by integrating the solutions that are obtained due to the concentrated jumps of the displacements and stresses. The obtained system is solved by using the method of orthogonal polynomials. We also determine the displacement jumps and the influence of the inclusion flexibility on the stress intensity factor.
