Electro-mechanical model and finite element implementation for discrete lattice model

Abstract

[EN] This work seeks to provide a formulation to simulate the microscopic behavior of a piezoelectric device and the corresponding macroscopic implementation into a finite element code for elastic and plastic regimes, such as [1]. To pull off this objective, a thermodynamically fully-consistent development of coupled mechanic and electric fields for ferroelectric materials has been established [2]. The formulation is implemented in the research Finite Element code FEAP.
