Abstract : The development of high-strength structural adhesives has created may new uses for adhesive joints and established a need for additional theoretical and experimental study. An adhesive lap joint is analyzed, taking advantage of its similarity to a sandwich structure for which an established theory exists. The principles of minimum complementary energy is used to develop the governing equations, which are equivalent to a single differential equation of eighth order. Included in the complementary energy expression are contributions due to shear and normal stresses in the adhesive layer and due to shear, axial, bending, and normal stresses in the adherend.
