LONGITUDINAL FORCED VIBRATION OF VISCOELASTIC BARS WITH END MASS

Abstract

A simple method is presented to measure the complex modulus of suitably rigid linear viscoelastic materials over the audiofrequency spectrum. The case is considered where one end of a rod of the material is driven harmonically and the complex displacement ratio is measured. The effect of a rigid end mass on the free end is accounted for. It is shown that, at specific frequencies near resonance, it is easy to obtain modulus data with standard equipment usually found in the vibration laboratory. An experimental program is described.
