Abstract: A mathematical model for the nonlinear hereditary viscoelasticity of polymer materials is proposed to predict deformation processes of various complexity – from simple relaxation and simple creep to complex deformation-relaxation and reverse relaxation processes with alternative loading and unloading.

Keywords: polymers, nonlinear hereditary viscoelasticity, stress-strain state.
