Abstract

In this article, amplitude, and vibrational characteristics of a rotating fiber metal laminated microdisk are presented. The current microstructure is modeled as a flexible microdisk surrounded by the two-parameter viscoelastic foundation. The centrifugal and coriolis effects due to the rotation are considered. The strains and stresses can be determined via the third-order shear deformable theory. For accessing to size-effects, the nonlocal strain gradient theory is used. The boundary conditions are derived through governing equations of the laminated rotating microdisk using an energy method known as Hamilton’s principle and finally are solved using a numerical method based generalized differential quadrature method.

摘要

本文介绍了旋转纤维金属层压微盘的振幅和振动特性。当前的微观结构被建模为由两参数粘弹性基础包围的柔性微盘。考虑了旋转引起的离心效应和科里奥利效应。应变和应力可以通过三阶剪切变形理论确定。为了获得尺寸效应，使用了非局部应变梯度理论。边界条件是使用称为 Hamilton 原理的能量方法通过层压旋转微盘的控制方程得出的，最后使用基于数值方法的广义微分求积法求解。
