Analysis of T-Peel Weld-Bonded Joint with Single Overlap Support
Bonded structure are commonly of three types, purely adhesive bonded, weld-bonded and adhesive/mechanical structures. Peel and overlapped joints are commonly used in the development of bonded structures. T-Peel bonded joint has week tensile strength load compared to double-overlap bonded joint. The present work aimed to predicting the strength of weld-bonded T-peel joint with single overlap weld-bond support plate using finite-element method. For comparison purposes, weld-bond T-peel joint without support is included in this study. It was found the peak stress is concentrated towards the inner far end of T-peel mid-layer of adhesive and through weld-nugget center. The introduction of single overlap weld-bond support for T-peel joint strengthen the joint by 500%.
