✦ Synopsis

This research presents an extended variational principle and a finite element formulation for multiphysics analysis of PLZT (lanthanum zirconate titanate) ceramics by including the photovoltaic and optothermic effects. The photo-induced electrical and thermal, and mechanical fields, as well as the heat source effect due to light illumination are all considered in the formulation. A generalized variation approach for advanced multi-physics PLZT problems is developed and then the relevant finite element formulation is established.

## Abstract A mixed variational principle is developed and utilized in a finite element formulation. The procedure is mixed in the sense that it is based upon a combination of modified potential and complementary energy principles. Compatibility and equilibrium are satisfied throughout the domain _
