In order to study the strength of the metal-FRP bounded joints, both of the finite element stress analyses and experiments have been carried out for T type bounded joints. It has been found that the fracture of the bonded joints, both the single lap joints and the T type joints, can be explained well by σ_<max> which is the maximum equivalent stress in the adhesive layer. The fracture occurs when σ_<max> reaches a critical value σ_f. σ_f is a constant for a specific bonded joint, and it can be estimated experimentally by the strength of a single lap joint. σ_<max> can be calculated efficiently by the developed stress analysis system. Therefore, the strength of the bonded joints can be estimated by the criterion, σ_<max> =σ_f, and the criterion is applicable to the structural design of the bonded joints.
