文摘

We present a complete formulation for thermo–electro–elastoplastic behavior that is developed in a consistent manner by using conservation principles along with the definition of a free-energy potential. FE implementation in the most general 3D framework, by using 8-node hexahedral finite element for constructing semi-discretization, along with the global phase of time discretization by the Newmark scheme. This development provides the sound basis for practical applications, such as the pulsed Peltier Cells.
