Vibrational Characteristics of C-C-C-C Visco-Elstic Plate with Varying Thickness

Abstract

Abstract

The main objective of the present study is to analyze vibrational characteristics of visco-elastic rectangular plate whose thickness varies in two directions. Two dimensional variation of thickness is considered as cubically in x-direction and linearly in y-direction. 4 Rayleigh- Ritz technique is used to get convenient frequency equation. Time period (K) and deflection (w) i.e. amplitude of vibrating mode at different instants of time for the first two modes of vibration are calculated for various values of taper constant and aspect ratio.

Keywords: Visco-elastic, recatngular plate, variable thickness and vibration.
