A general solution for static piezothermoelastic problems of crystal class 6mm solids

摘要

In this paper, a general solution for three-dimensional static piezothermoleastic prob- lems of crystal class 6mm solids is presented. The general solution involves four piezoelastic potential functions and a piezothermoelastic potential function, of which four piezoelastic potential functions are governed by weighted harmonic differential equations. Compared with the general solution given by Ashida et al., in which seven potential functions are introduced, the general solution proposed in the Present paper is more rigorously derived.
