Amplitude-dependent dynamical behavior of poly(methyl methacrylate)

Some results on the amplitude-dependent dynamical behavior of poly(methyl methacrylate) are presented. Both the loss tangent (internal friction) and the storage Young’s modulus are strain-amplitude-dependent, when measured between room temperature and approximately 400 K, at a frequency of the order...
