摘要：
Adhesive in joints will have complex stress state rather than bulk adhesives, This will lead to the assumption behind bulk adhesive that triaxiality function (R-v) is equal to one (uni-axial stress state) is not valid anymore. In this paper, new procedure to find damage parameters alpha and beta for single-lap joints has been developed based on global damage of adhesive joints. With this procedure, damage parameters alpha and beta have been found. Validating the procedure by calculating the number of cycles to failure (N-f) has been performed successfully. The accuracy of the damage evolution equation is less than 2 %.
