An Experimental Determination of the Dynamic Young's Modulus of Selected Viscoelastic Materials.

Abstract

Viscoelastic materials or elastomers are widely used to isolate transmission of vibrations. The elastic characteristics of these materials can be understood if the bulk, shear and Young's moduli are known. In this study, results of the dynamic characteristics of the Young's modulus over a wide range of frequencies were obtained for eight different elastomers. Samples of the different viscoelastic materials were attached to an oscillator and different vibratory frequencies were excited. Voltage and phase difference of the waves propagating along the elastomers were recorded by means of a stereo pick-up and graphs of voltage versus distance and phase versus distance were drawn in order to obtain the attenuation constant and wavelength, respectively.
