Abstract


The hybrid formulation based on experimental data and the finite element procedure seems to be able to predict crack initiation under fatigue conditions for single lap joints aged by UV exposure. The UV exposure decreased stiffness and strength. The addition of graphene seems to postpone such ageing. However, by considering that cracks initiates when the (TS/σVM)~1. “Soft†adhesives can reach longer fatigue life at low loadings, while “stiff†adhesives have its fatigue life drastically decreased but at higher loadings. Stiff adhesives are more suitable for low cycle fatigue conditions, while for high cycle fatigue the option is a soft adhesive.
