摘要

摘要:根据线弹性理论以及电介质理论推出了类似于Ｂｅｔｔｉ互等功定理的热电弹性耦合体─—热释电弹性体的互等功方程；作为一种应用推导了在边界积分方法中被广泛采纳的热电弹性Ｓｏｍｉｇｌｉａｎａ方程．

Abstract:With the linear elastic theory,theory of dielectrics and thermal conduction theory,the equations of work reciprocity similar to Bett’s theorem of work reciprocity are derived for pyroelectric elastic media.According to the equations,the pyroelectric elastic Somigliana’s boundary integral equalities were presented, which can be widely applied to boundary element method.
