A computer aided design (CAD) system was developed in order to establish the systematic strength design method of adhesively bonded joints. This system was composed of two parts as follows : (1) the stress analysis and the strength prediction were performed using the finite element method and the strength criterion, and (2) the optimum adhesive length and other dimensions of the joint were determined by the predicted joint strength. This method was applied to the design of single lap joints, scarf joints (including butt joints) and shaft joints. It was verified that this system could be successfully applied to the stress analysis of joints using the auto-meshing processor and the finite element method processor, and to the prediction of joint strength using the strength criterion. The relation betwees joint strength and dimension were graphically obtained. The optimum adhesive length and other dimensions of joints could be chosen by the graphic representation of joint strength under static loadings.
