In this study, the three-dimensional finite element method is used to analyze the effects of the thermal residual stresses due to the adhesive curing on the efficiency of bonded composite repair of cracked aluminum panels. The variation of the stress intensity factor at the crack tip is used for evaluating the repair performances. The effects of the geometrical and the mechanical properties of the composite patch and the adhesive on the repair efficiency were highlighted. The obtained results show that the thermal residual stresses significantly increase the stress intensity factor at the crack tip which reduces the repair efficiency.

In this study, the distribution of the thermal residual stresses due to the adhesive curing in elliptical and circular bonded composite repairs is analyzed using the finite element method. The computation of these stresses comprises all components of the structures: cracked plate, composite patch and adhesive layer. In addition, the influence of these residual stresses on the repair performance is highlighted by analyzing their effect on the stress intensity factor at the crack tip. The obtained results show that the normal thermal stresses in the plate and the patch are significant.. The presence of the thermal stresses increases the stress intensity factor at the crack tip which reduce the repair efficiency.
