Bonded joints with composite adherends. Part II. Finite element analysis of joggle lap joints

This paper describes a finite element analysis of two adhesive bonded joint configurations, namely single lap joint and joggle lap joint, for which an extensive experimental analysis had been made previously. The adherends were assumed to behave as linearly elastic materials, while the adhesive layer was assumed to be nonlinear. The nonlinear geometric deformations of the joint were also taken into account. The numerical results agree well with the experimental results up to 2000 N. Moreover, the distinctive geometric deformations observed experimentally with the joggle lap joint under loading were accurately predicted by the finite element model.
