The strength of stepped-lap bonded joints with metal adherends is investigated both analytically and experimentally. The effect of the number of steps on the joint strength is discussed. The joints used in this study have adherends of carbon steel, brass and aluminum alloy and adhesive of epoxy resin. The strain and stress distributions under a tensile shear load are analyzed by applying the finite element method. The initial cracking and final fractured loads are predicted by applying the strength laws to the adherend, adhesive and their interface. The analytical results show good agreement with the experimental ones. Though the initial cracking loads are not affected by the number of steps, the final fracture strength of the joint is improved by increasing the number of steps.
