Amplitude-dependent dynamical behavior of PVC

Results of the amplitude-dependent dynamical behavior of commercial poly(vinyl chloride) are presented. Both the loss factor (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 50 kHz...
