Abstract:

A method is provided for determining the axial modulus of an elongate material sample of mass density p and length L. The first end of the sample is driven longitudinally at a frequency of excitation omega. The second end of the sample opposite the fIrst end may or may not be under tension. At the frequency of excitation omega, the longitudinal displacement and longitudinal force at the first and second ends of the sample are determined. The axial modulus is calculated for any frequency as a function of mass density p, length L. frequency of excitation omega, and longitudinal displacement and longitudinal force at the first and second ends.
