Application of composites in Civil engineering, such as repair of bridges and piers by graphite-epoxy composites, is growing rapidly. One of the concern in composite materials is interface debonding between the fiber and matrix. We employ an analytical model considering partial debonding along fiber's interface, and construct a finite element, in which a scheme to calculate the stress re-distribution due to the partial debonding is included. Several numerical examples and comparisons with experimental data show the characteristics and feasibility of this model.
