Stress Concentration Due to an Oblate Spheroidal Inclusion.

Abstract

The stress concentration of an oblate spheroidal inclusion parallel to the stress and deformation axis is obtained by using Eshelby theory. This is complementary to our previous study, in which stress concentration is analyzed for an oblate spheroidal inclusion normal to the stress and deformation axis. Effects of the elastic stiffness and the aspect ratio of the inclusion on the stress concentration are examined in detail. The internal stresses inside the inclusion and at the matrix-inclusion boundary are calculated considering inhomogeneity and plastic deformation effects. Stress concentrations at graphite flakes and nodules in cast iron are discussed. (Author)
