Constitutive relations for viscoelastoplastic materials at small strains |

| Abstract |
A thermomechanical approach to the modeling of viscoelastoplastic
materials at small strains is presented which allows the
experimentally observed effect of strain rate hardening of materials,
resulting in the dynamic yield stress exceeding the static yield
stress, to be described. An analysis of P. Perzyna's viscoplasticity
equations is carried out first, the equations being presented in an
alternative, though mathematically equivalent, form which agrees with
A. A. Il'yushin's macroscopic determinability principle.
The dynamic yield criteria (in stress and strain spaces) are derived,
together with the relationships for the irreversible strain variation laws
which are shown to coincide with the associated plastic flow rules. The
results obtained agree with the classical ones. For the corresponding
material parameters, the Tresca-Saint-Venant, Huber-Mises,
Ishlinskii-Prager, and Kadashevich-Novozhilov yield criteria are
obtained, as well as the Ivlev-Ishlinskii, Kaliszky, and Perzyna
dynamic yield surfaces. The constitutive relations considered cover,
as the limiting cases, the Kelvin, Maxwell, and Voigt viscoelastic body
models. The approach developed enables also the elastic (mechanical)
hysteresis to be taken into account. |
