The elasto-plastic finite element method (FEM) is applied to investigate the effect of contacting forms of steel mosaic block on the stress distribution in the aluminum single lap joint. The results obtained show that the stress in the joint was changed evidently. A couple of compress longitudinal peak stress and a negative peel stress occur in the mid-bondline of the joint so that the load bearing ability of it may be increased when there was a steel mosaic block. The form of mosaic joining to the adherend is very important to the stress distribution in the joint. When the block was adhesively bonded at up and down faces and contacted at both sides, the block may rotate together with the adherend while the joint deformed under load, which led the ends of the block contacted to the adherend. The value of the peel stress Sy increases so that it is beneficial to transfer the axial stress and shear stress into the mosaic block. It is suggested that a suitable mosaic mode be chosen when it is demanded to improve the adhesively bonded joint.
