Calculation of Stress-Strain Curves from Relaxation Data in the Rubbery- Flow Region

Abstract

Time dependent, stress relaxation curves for polysulfone and lexan polycarbonate at constant temperature are obtained. The strain independent stress relaxation curves can be used to calculate stress-strain curves at different rates of strain according to the linear viscoelastic theory. The agreement between experimental and calculated stress-strain curves is good at least up to about 60% strain in the range of 0.01 to 0.2 in/min rate of extension.
