Abstract: Endochronic constitutive equations in viscoplastic theory for large strain domain are studied. For some deformation gradients equations solving non-elastic problem are analyzed. Theoretical behavior of materials is demonstrated at creep and stress relaxation conditions. Obtained results are compared to experimental data and results obtained by other researchers.

Keywords: non-elasticity, creep, relaxation, large strains, endochronic theory, constitutive equations.
