Abstract

This article studies free vibration of a functionally graded porous cylindrical small-scale shell made from porous metal and ceramic based on power law distribution. It is bonded with an adjustable array of strip-like piezoelectric elements. The behavior of integrated structure is modified by change of quantity and location of the elements. Motion equations are achieved through first-order shear deformation theory and principle of virtual work. Stress-strain relations are developed via nonlocal theory. Two comparative studies are presented for validation of formulation. A parametric study is reported to investigate effects of input parameters.

与任意压电元件阵列集成的功能梯度多孔圆柱形纳米壳的非局部振动特性

摘要

本文研究了基于幂律分布的由多孔金属和陶瓷制成的功能梯度多孔圆柱形小型壳的自由振动。它与可调节的带状压电元件阵列结合在一起。整体结构的行为随着元素数量和位置的变化而改变。运动方程是通过一阶剪切变形理论和虚功原理实现的。应力-应变关系是通过非局部理论发展起来的。提出了两项​​比较研究以验证配方。据报道，一项参数研究调查了输入参数的影响。
