The asymptotic stress field for a rigid circular inclusion at the interface of two bonded dissimilar elastic half-space materials
Intemational Joumal of Solids and Structures 38(2001)8091-8035,-0001,():
The paper considers three-dimen sional interface inclusion problems The axisymmetric elastostatics problem of a rigid circular inclusion at the in terface between two perfectly bonded dissimilar elastic half spaces is analyzed. Based on the representations of displacements and stresses in terms of Love's atrain potential and the Hankel transform tech-nique the mixed boundary value problem assoiciated with a rigid circular inclusion at the interface reduces to a pair of simultaneous integral equations for the stress jumps across the inclusion, which are further transformed to a single singular integral wquation For the case of uniform axial and radial tension s at infinity, the as ymptotic stresses near the inclusion front are obtained and they exhibit the oscillatory sin gularity. Meanwhile, the magnitude ofthe singularity for the interface inclusion depends on the material constants of the upper and lower half spaces, the dependence fo sin-gularity coefficients on material constants for interface inclusion problems, however is different from that for interface
