Stress distributions and joint strength of stepped-lap adhesive joints of dissimilar adherends subjected to static tensile loadings are analyzed using three-dimensional finite-element method. Steel and Aluminum are chosen as Adherend materials. In addition, the stress distributions in the joints of similar adherends are also analyzed. The FEM code name employed is ANSYS. The effects of Young's modulus of the adhesive, adhesive thickness, number of butted steps and scarf angle of the adherends on the stress distributions at the adhesive interfaces are examined. As the result, it is found that the maximum value of the maximum principal stress σ_1 decreases as Young's modulus of the adhesive increases. For the verification of FEM calculations, experiments to measure the strains in the joints were carried out using strain gauges. A fairly good agreement is found between the calculated and the measured results concerning the strains.
