周边简支空心压电圆板表面均载弯曲

A simply supported hollow circular piezoelectric plate under uniform load

本文利用横观各向同性压电材料的通解和所构造的三个调和函数，给出了受均布载荷的周边简支空心圆板的解析解，退化得到实心圆板的解，比较了ＰＺＴ－４实心圆板和与ＰＺＴ－４有相同弹性常数的横观各向同性圆板的中心挠度和弯矩．

In this paper,three harmonic functions are constructed.As a result the solutions of simply supported solid and hollow circular piezoelectric plates subjected to uniform load are given by using the general solution for transversely isotropic piezoelectric materials.At last,the displacement and bending moment at the centre of a PZT 4 solid circular plate and a transversely isotropic solid circular plate,which has the same elastic constants as the PZT 4,are compared with each other.
