Gurtin-Type Region-Wise Variational Principles for Thermopiezoelectric Elastodynamics

Department of Applied Mechanics, Beijing Institute of Technology, Beijing 100081, P.R.China

摘要: 建立有关压电热弹性动力学的各种Gurtin型分区变分原理,由此变分原理可以得到压电热弹性动力学所有方程式、关系式和边界条件,并且可以直接得到各相邻区域交界面上的连续条件。Gurtin型分区变分原理是压电热弹性动力学的重要组成部分,并能反映压电热弹性动力学初值-边值问题的全部特征。

Abstract: The variation of new Gurtin-type region-wise variational principles results in continuous conditions,boundary conditions,all equations and relations in linear thermo piezoelectric elastodynamics.Gurtin-type region-wise variational principles comprise very important parts of linear thermo piezoelectric elastodynamics,and can fully characterize the initial-boundary-value problem in linear thermopiezoelectric elastodynamics.
