In many applications of piezoelectrically controlled smart structures, the functionality of the system has to be guaranteed in extremely hot and cold thermal environments. Consequently, the thermal effect is very important and must be taken into account in the design process of such structures. This results in a fully coupled formulation of piezothermoelastic material behaviour. Based on a weak formulation of the equilibrium conditions and the coupled constitutive equations of this three field problem a general finite element concept is presented. Static as well as dynamic responses of combined thermal, electric and mechanical excitations are considered. An iterative solution strategy is proposed to solve the coupled field problem in an effective way.
