constant oscillation-amplitude method

https://doi.org/10.1351/goldbook.12753
Forced-resonance method to determine the viscoelastic properties of a material.
Note: Indirect measurement of the energy that has to be added to a material sample to compensate the damping of the oscillation by determination of the change of the resonance frequency of a material sample.
