Partial debonding along interface of inclusions becomes a important problem in the initial stage of fracture phenomena of composite materials. We employed a debonding model that take stress transmission characteristics of inclusion into account, and built this model into 3-dimensional finite element. In addition, a numerical procedure to calculate the stress redistribution due to the partial debonding has been considered. Simple numerical examples show characterristics and feasibility of this model.
