Partial debonding along interface of inclusions becomes an important problem in the initial stage of fracture phenomena of composite materials. We here employed a debonding model that takes stress transmission characteristics of inclusion into account, and built this model into a finite element. In its numerical procedure, stress re-distribution due to softening effect by developing debonding was considered. Furthermore, from a different point of view, damage model was introduced to take progressive debonding effect into account. Simple boundary value problems were solved to show feasibility of the models.
