Order of singularity and singular stress field about an axisymmetric interface corner in three-dimensional isotropic elasticity

The spatial axisymmetric problem of an isotropic\ elastic\ homogeneous body containing an inclusion of a di}erent material with an interface corner point "along a circular contour# and arbitrary joining angles is considered in this paper[ It is found that the order of the stress singularity at the interface corner coincides with that of the corresponding plane strain problem\ but the dependence of the singular stress _eld on the material properties depends on both the Poisson ratios "of the two isotropic materials# as well as on the ratio of their shear moduli[ The theoretical results have been con_rmed by numerical\ _nite!element!based results in a special bimaterial case[
