Abstract
In this paper, the axisymmetric bending problem of a perforated plate which consists of two bonded isotropic dissimilar materials is considered. The problem is of interest in the delamination failure study of multilayered composites. From the plane elasticity solution of bonded isotropic materials, it is well-known that the interface stresses have a weak power singularity near the free boundary and this in turn may enhance the possibility of delamination failure. The solution given in this paper is based on the method developed in [1]. An elasticity series solution of the axisymmetric bending problem is presented. This can be considered as the first component of the general bending problem. The stresses exhibit the expected singular behavior around the hole boundary. The results are also compared with those obtained by using the Finite Ele ment Method. It is observed that the two sets agree rather well with regard to trend and magnitude of interface stresses.
