점탄성 재료로 구속 감쇠 처리된 복합 적층판의 진동 및 감쇠 해석 Vibration and Damping Analysis of Laminated Plates With a Constrained Viscoelastic Layer

The finite element method based on the layerwise displacement theory and the modal strain energy method is applied for the vibration and damping analysis of composite plates treated with a constrained viscoelastic layer. Through several numerical examples, the effects of stacking sequences, side-to-thickness ratios of the plate, locations of partial coverage, and the thicknesses of the viscoelastic layers on vibration and damping characteristics are investigated. The developed model is a versatile tool that can be easily used to analyze the plate with general boundary conditions and stepped configurations (change in thickness) due to a partially constrained viscoelastic layer. This is due to the fact that each 2-dimensional element can retain different degrees of freedom for the in-plane displacement through the thickness of the layers.
