Publication Date



In this paper, a mathematical model to study the transverse vibration and damping of an adhesively bonded tubular lap joint is presented. The governing equations of motion of the system for the case of forced vibration are first 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 bending deformation of the adhesive layer. By using the finite difference method, the numerical solutions of the governing equations for free vibration under fixed-fixed boundary conditions are obtained. The effects of structural parameters and material properties of the adhesive layer on the system modal loss factors and resonance frequencies are also studied. © 1994 Academic Press Ltd.
