Numerical predictions of the tensile stresses within adhesively-bonded aluminium T-peel joints have established where critical fatigue defects are likely to initiate and propagate to fracture. These predictions of maximum stress correlate directly with static strength measurements of such joints. The results presented within this article elucidate the region of cohesive crack initiation, its subsequent direction of propagation and the relative duration of the different stages of fatigue crack growth. Separate stages of embedded, surface and through-width fatigue growth of cohesive defects with a T-peel joint are identified and compared. In this manner the fatigue life of typical bonded aluminium-epoxy T-peel joints has been established from the first stages of crack initiation to final joint fracture. It has been shown that joint static and fatigue strengths are maximized by having a maximum amount of adhesive within the fillet region of the joint.
