3D Model of Coupled Multi-physics Fields for PLZT Ceramics and Its Applications to Photostrictive Plates
Source abstract
Abstract
This article investigates an extended 3D model for coupled opto-electro-thermo-mechanical fields in PbLaZrTi (PLZT) ceramics by incorporating the photovoltaic, optothermic, and pyroelectric effects into the existing thermopiezoelectic model. The 3D model is then used to establish novel governing equations for 0-3 polarized orthotropic PLZT plates. Actuating and sensing behaviors of 0-3 polarized PLZT plates subjected to light illumination and mechanical loading are then studied. Stress analysis is conducted for a 0-3 polarized PLZT plate with free boundary conditions. Analytical solution for a simply supported photostrictive plate partially subjected to light illumination is derived. Numerical results for free and simply supported photostrictive plates illuminated by light are calculated using the present formulations and finite element analysis.
