Abstract

The stress distribution at the interface corner between three elastic materials is examined. Depending on the material properties and the geometry at the interface corner, singular stress fields of the form Hr^{lamda-1} may exist at the corner. Here H is the intensity of the stress field associated with the eigenvalue lambda and r is the radial distance from the interface corner. The intensity H was evaluated using a contour integral in conjunction with the finite element method. Closed form solutions for the stress and displacement fields near the interface corner are presented and compared with the finite element prediction.
