The model for macro-deformation is based on an Arrhenius-type equation. Using a thermodynamic approach, an analysis is described which characterizes the deformation behaviour by activation enthalpies, stress-and pressure-activation volumes and frequency factors, and their relation to stress, pressure and strain. The application of the method in recent experiments on EP, PE, PMMA, etc. is reviewed, and the consistency of theoretical and experimental results is demonstrated.
