Notes:
Non-linear stress relaxation data were obtained for polycarbonate and polystyrene as a function of temperature, strain magnitude and thermal history. Data were analyzed according to the previously proposed free volume model to account for the shift of relaxation times with strain and thermal history. The result of the analysis is shown to be in close agreement with the tensile stress-strain data. The yield phenomenon is analyzed as a rate dependent strain-induced glass to rubber transition.
