| 摘 要： | 磁电弹性耦合材料的力学本构方程一般形式是通过应力、电位移、磁感应强度来表示应变、电势和磁势。文章根据连续介质的热力学理论,利用Gibbs自由能和Legendre变换,系统地推导了磁电弹性耦合材料8种形式的本构方程,为磁电弹性耦合材料的进一步研究提供了理论基础。

| Abstract: | The constitutive relationship of magneto-electrio-elastic coupling materials is a set of equations in which the strain,electric potential and magnetic potential are expressed in terms of the stress,electric displacement and magnetic induction strength.In this paper,according to the thermodynamic theory of continuous medium and using the Gibbs free energy and Legnedre transformation,eight different types of constitutive equations of magneto-electrio-elastic materials are presented.The study may be useful to future investigation of magneto-electrio-elastic materials. |
