Finite element modeling of electro-mechanically coupled analysis for ferroelectric ceramic materials with defects

摘要

In light of the equations of static mechanical and electrical equilibrium of ferroelectric materials, the functional is presented by using the principle of virtual work in this paper. Formulation of the electro-mechanically coupled finite element analysis for ferroelectric materials with defects has been described in details. The effect of depolarization in ferroelectrics has been taken into account in the formulation.
