✦ Synopsis

An isoparametric adhesive interface element is used in the vibration analysis of adhesively bonded structures. It is assumed that transverse shear and peel stresses prevail in the adhesive layer. The analyses articulate separate responses of the upper and lower adherends and the adhesive. The natural frequencies of laminated plates with a lap-joint are found to be reasonable when compared with the results for plates without joints. The present element, together with the eight-node isoparametric plate element based on a first order shear deformation theory used to model the upper and lower adherends, is found to be effective in solving free vibration problems of adhesively bonded laminated lap-joints.
