Coupled extensional and torsional deformations of a piezoelectric cylinder
نویسندگان
چکیده
We derive a one-dimensional model from the three-dimensional equations to analyze electromechanical deformations of a piezoceramic cylinder. We show that its extensional and torsional deformations are coupled if the axis of polarization at a point makes a nonzero angle with the axis of the cylinder and the projection of the polarization vector on a cross section is perpendicular to the radial line through the point.

Temperature Effects on Nonlinear Vibration of FGM Plates Coupled with Piezoelectric Actuators
An analytical solution for a sandwich circular FGM plate coupled with piezoelectric layers under one-dimension heat conduction is presented in this paper. A nonlinear static problem is solved first to determine the initial stress state and pre-vibration deformations. By adding an incremental dynamic state to the pre-vibration state, the differential equations are derived. The role of thermal en...
