Limitations of the Tobolsky 'Two Network Theory' in the Interpretation of Stress-Relaxation Data in Rubbers

摘要

Experiments have been devised which reveal serious shortcomings in the accepted method of interpreting the results of continuous and intermittent stress-relaxation measurements in terms of the Tobolsky 'two network theory'. In general the heat ageing of rubbers is a omplex process and there is a high probability that the results of stress-relaxation measurements will not be amenable to analysis by the 'two network theory'.
