BASIC EQUATIONS FOR FERROELECTRICS

摘要：

A set of new formula of energy functions for ferroelectrics was proposed,andthen the new basic equations were derived in this paper.The finite elementformulation based on the new basic equations was improved to avoid the equivalentnodal load produced by remnant polarization.With regard to the fundamentals ofmathematics and physics,the new energy functions and basic equations arereasonable for the material element of ferroelectrics in finite element analysis.
