摘要：
A crack is assumed to emanate from the tip of bonded dissimilar materials with the crack on the bisector of one of the bonded wedges. The problem is firstly divided into symmetric and anti-symmetric modes according to the characteristics of the local geometry. By eigenexpansion method, the eigenequations for the two modes are derived, respectively, and the corresponding eigenvalues are obtained with different ratios of dissimilar material 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 an explicit form.
