AFFECTION OF
THICKNESS OF VISC- OELASTIC CORE AND CONSTRAINED LAYER IN LOSS
FACTOR OF PLATES*
Abstract: A new method for vibration damping analysis of general multi-layered rectangular plates consisting of arbitrary number of layers of orthotropic materials has been developed by method of basic elastic equation and Tailor series. The solution for a multi-layered plate with simply supported edges has taken in series summation form and resonating. Affection of thickness of viscoelastic core and thickness of constrained layer has been considered and the solution of a calculation example has been got. Present method also could be used for mechanical performance and damping analysis of composite plates.
