基于不同梯度模式压电功能梯度板的挠度与应力场分析

用解析方法模拟压电功能梯度材料物性参数沿空间分布的非线性特性.基于物性参数沿空间为多项式函数、非整数幂函数及e指数函数分布3种不同梯度模型，采用修正的层合板理论，对压电功能梯度材料平板的挠度及应力场进行了分析，并对数值结果进行对比研究.

Analyses of In-plane Stress and Out-of-plane Displacement of Piezoelectric Functionally Graded Plates Base on Different Gradient Models

On the basis of three different gradient models which are polynomial function,fraction power function and exponent function respectively,we simulated the nonlinear characteristics of distribution of physical properties of the across the thickness of piezoelectric functionally graded material by means of analytic theory and obtained the in-plane stress and out-of-plane displacement by the modified classical lamination theory.
