摘要：
A crack is assumed to emanate from the tip of bonded dissiumilar materils wiht the crack on the bisector of one of the bonded wedges. The problem is firstly dividedinto symmetric and anti-symmetric modes accrding to the characteristics of the local geometry. By eigenexpansion method. the eigenequaitons for two modes arederived, respectively, and the corresponding eigenvalues are obtained wiht differentratios of dissimilar moaterial constants and angles of the wedges. The singularity of the crack is then analyzed by the eigenvalues that are less than one. The fields of displacement and stress in the vicinity of the tip of the crack are finally derived in anexplicit form.
