A Finite Element Procedure for Three-dimensional Analyses of Thermopiezoelectric Structures in Static Applications

Abstract

The development and application ofsmart structures and smart composite materials require eflicient numerical tools to evaluate the thermopiezoelectric behavior and stress state. In this paper, finite element techniques are suggested for three-dimensional coupled thermo-electromechanical static analyses. The actual thermopiezoelectric responses subjected to thermal loadings can be determined by adopting a procedure TPESAP. The detailed implementation is presented with emphasis on the integration with software ABAQUS. Several verification example problems are discussed, including the benchmark problem ofafive-layer hybrid plate.
