Nonlinear Vibration Analysis of Rotating Composite Plates Based on a Refined Plate Theory

개선된 판이론을 이용한 회전하는 복합재료 적층판의 비선형 진동해석

A refined plate theory including the effects of transverse shearing is used to predict the free vibration frequencies, mode shapes and stress distributions in spinning laminated composite plates. In this theory, the displacements are expressed by trigonometric series representation through the thickness. In the series for the displacements only the first few terms are retained. The model is validated by comparing the results for isotropic plates with those available in the literature.
