摘要：
A general solution procedure is proposed for plane-stress problems of circular plates constructed from piezothermoelastic material. potential functions are introduced in order to uncouple the equations governing equilibrium and electrostatics. The present formulation is applicable to plates having arbitrary edge conditions. Solutions are derived for plates having either radially constrained or traction-free edges and subjected to axisymmetric surface heating. Numerical results illustrate the effects of plate thickness and variations in material properties upon the induced elastic displacements, stresses, electric potential and electric displacements.
