In this work, a novel, analytical and realistic model has been developed to investigate the stresses of bonded composite patch reinforcement to metallic plates that accounts for the effects of large deflections both outside and inside the overlap. The model is designed to deal with the one-side bonded reinforcement and it is able to compute axial tension force, bending deflections, and interfacial stresses of the bondline and interlaminar stresses throughout the patch. A comparison study with numerical simulation indicates that shear and peeling stresses from present methods generally match very well with finite element results, except for the peak values near the free edge. The present solution predicts larger peak values, which may be caused by the assumption of identical displacement in both the substrate and the patch and the effects of large deflections. Present work may provide a rapid and accurate solution to the stress analysis and design of bonded composite patch reinforcement to metallic structures after uniform corrosion.
