Abstract
In this paper, an intensity of singular stress field for a bonded cylinder under a bending load is calculated. The analytical method focuses on the stress values at the interface corner edge obtained by performing FE analyses on the unknown and reference models which are subdivided by the same mesh pattern. Then the debonding fracture criteria are examined in terms of the intensity of the singular stress appearing at the corner of butt joints by using the previous results of four-point bending experiments.
