Finite element analyses were conducted for Al/epoxy butt joints under remote tension, and the singular stresses near the bond edge were determined by the displacement method. The edge singular thermal stresses of the joint caused by uniform temperature change were obtained based on the superposition principle from the solution of singular stress due to remote tension. When the joint was under fatigue loading below the glass transition temperature of epoxy resin, the singular term corresponding to the stress range or the mean stress became frequency dependent or time dependent. Variation of strains near the bond edge of the joint under fatigue loading was well predicted by the analysis with material properties approximated as linear elastic.
