COMPARISON OF COMPLEX MODULI OBTAINED FROM FORCED AND FREE DAMPED OSCILLATIONS.

Abstract

An analysis of a generalized Maxwell model, representing a viscoelastic solid under conditions of forced and free oscillations shows that the complex modulus computed from the two types of motion are not identical but the approximation provided by a free vibration experiment is reliable when tan delta is less than 0.6. The free vibration experiment over estimates damping and under estimates the modulus. (Author)
