The cyclic constitutive equations developed at ONERA have been incorporated into a general thermodynamic framework (Part I). In the present part, systematic comparisons are given between the model predictions and experimental data for both the mechanical response and the energy stored in the material. The models are specified in their rate—independent-form and closed-form solutions are obtained for tension-compression monotonic and cyclic conditions. By superposing one or two nonlinear kinematic rules and one isotropic hardening equation, the available experimental data are fairly well reproduced. In particular it is possible to describe the low values of stored energy, the decrease of the ratio of stored energy to total plastic work as a function of strain, and the partial release of stored energy at every half cycle of a cyclic loading.
