Shape Control and Vibration Analysis of Pi-ezolaminated Plates Subjected to Electro-Mechanical Loading

Abstract

Shape control and free vibration analysis of piezolaminated plates subjected to electro mechanical loading are evaluated using finite element method. First order shear deformation theory is e m- ployed in the analysis. Both extensions as well as shear actuators are considered for piezolam i- nated plates. Rectangular four node isoparametric element is used in the finite element formul a- tion. Variation of temperature is neglected for the orthotropic layers of the laminate and for pi e- zolayer. Annular circular plate s and rectangular plates with piezoelectric layers mounted and/or integrated are analysed for various parameters. Numerical results are presented for varying the actuator voltage for annular plates with different thicknesses of piez o patches. In case of rectan- gular plate shear actuator is considered for vibration analysis.
