Paper Abstract

The measurement of the bulk longitudinal modulus, M*, of rubbery polymers is a notoriously difficult task. Measurements are traditionally done through wave transmission through a fluid environment in methods that provide M* over only very narrow frequency ranges. An alternative approach, using a resonant test fixture, is presented in this paper. A discussion of some physical limitations is developed. Among them are issues of repeatability and edge effects. A method of data analysis to address edge effects also is presented.
