An experimental and numerical analysis on welded, adhesive, and hybrid (weld-bonded) T-peel joints under peeling loads is described in the present work. The called adhesives included the brittle Araldite ® AV138, the moderately ductile Araldite ® 2015 and the ductile Sikaforce ® 7752. An analysis of the experimental values and a comparison of these values with the Finite Element Method (FEM) results was carried out in Abaqus ®, which included Cohesive Zone Models (CZM) strength prediction considering simulation of the adhesive layer as well as weld-nugget failures. The Sikaforce ® 7752 has been found to perform best in the bonded and hybrid configurations. The strong agreement between the experimental and numerical results made it possible to predict the power of the adhesive and hybrid T-peel joints through CZM validation. CZM is a computational technique focused on traction-separation laws integrating stress principles with fracture mechanics to predict structural strength, including bonded joints. In reality, the initiation of damage, i.e. the cancelation of the elastic behaviour and the depreciation of strength, is predicted by strength-based criteria, while failure of the CZM elements is predicted by energetic criteria, allowing the simulation of damage growth to failure.
