Modelling of Electroelastic Behaviour of Embedded Piezoelectric Actuators in Smart Structures: 2D and 3D Effects
A two-dimensional electroelastic model of embedded piezoelectric actuators was proposed to study the coupled electromechanical behaviour of a thin piezoceramic actuator embedded in an elastic host structure under applied stresses. Interfacial normal and shear stresses for both plane stress and plane strain deformations were calculated to evaluate the actuation effects transferred from the actuator to the host structure. Three dimensional analyses were also conducted using the finite element method to validate the present model by comparing the two results for specific examples. It was observed that the current model provided reasonable prediction of the load transfer by the actuator.
