Abstract

This paper presents a dynamic model for the transverse vibration analysis of an adhesively bonded composite double-strap joint. The differential equations of motion of the joint system are derived using the energy method and Hamilton's principle. It is assumed that the energy dissipated by the joint system is contributed by both the shear and longitudinal deformation of the adhesive layers. The combination of natural boundary conditions, forced boundary conditions, and continuity conditions yields the frequency equations to predict the system resonance frequencies and modal loss factors. The effects of structural parameters and material properties of the adhesive layer on the system modal loss factors and resonance frequencies are also studied.
