NONLINEAR HEREDITARY MODEL INCLUDING TEMPERATURE EFFECTS IN VARIOUS STRESS STATES

For an isotropic viscoelastic medium subjected to uniaxial loading, it has been shown that the parameters of the material (three parameters and the instantaneous deformation curve) can be determined on the basi s of a limited number of experiments. These same parameters were used in calculating a complex stress state. Results are presented for vario us temperatures and loading rates. Experimental data have been compare d with the results of theoretical calculations. Formulas for determini ng the resolvent of the hereditary equation have been derived.
