On the Dynamic Behaviour of Surface-Bonded Piezoelectric Sensors/Actuators with Partially Debonded Adhesive Layers
The current work presents the analytical study of the effect of the mechanical and geometrical properties of the adhesive layer on the coupled dynamic electromechanical behaviour of thin piezoceramic sensors/actuators bonded to elastic media.A sensor/actuator model with an imperfect adhesive bonding layer is proposed to simulate the two dimensional electromechanical behaviour of the integrated system.The analytical solution of the problem is provided to study the effect of the bonding layer upon the dynamic behaviour of the sensors/actuators under different loading frequencies.The interfacial debonding and its effect on the interlaminar strain and stress transfer mechanisms are discussed in detail.Numerical results obtained show that even for perfectly bonding cases the dynamic coupling between the sensors/actuators and the host structure is significantly affected by the material and geometric properties of the bonding layer.For imperfect bonding layers,debonding and loading frequency interact strongly to each other at certain frequencies,showing a significant coupling effect.
