Nonlinear mechanical spectrometry of poly(methyl methacrylate)

Data on the damping spectra of commercial poly(methyl methacrylate) (PMMA) are reported, both at low (of the order of 1 Hz) and at intermediate (of the order of 50 Hz) frequencies. It is shown that the damping does not only depend strongly on temperature and frequencies. It is shown that the damping...

It is shown that the damping does not only depend strongly on temperature and frequency but also on the strain amplitude applied to the specimen.
