“…The nonproportional hardening was repeatable, indicating that the behavior is not isotropic. Moosbrugger and McDowell (1989) and McDowell (1994) concluded that nonproportional hardening was essentially only of kinematic type for stainless steel 304. McDowell (1985b) showed that a two-surface Mroz-type model can be used for describing nonproportional loading.…”

“…In general, two approaches have been employed to derive constitutive models: (i) phenomenological/empirical and (ii) crystal plasticity-based (CP) mechanistic models. The former approach does not describe the plastic deformation occurring in each individual crystal but rather proposes to directly describe the response of the polycrystal [17][18][19][20][21][22][23][24][25]. These methods are numerically efficient and have successfully been used to predict the deformation behavior of metals under monotonic loading, creep conditions [17,20,[26][27][28], and cyclic loading [18,19,21,[29][30][31][32].…”

Predictions of the mechanical response of structural elements are conditioned by the accuracy of constitutive models used at the engineering length-scale. In this regard, a prospect of mechanistic crystal-plasticity-based constitutive models is that they could be used for extrapolation beyond regimes in which they are calibrated. However, their use for assessing the performance of a component is computationally onerous. To address this limitation, a new approach is proposed whereby a surrogate constitutive model (SM) of the inelastic response of 316H steel is derived from a mechanistic crystal plasticity-based polycrystal model tracking the evolution of dislocation densities on all slip systems. The latter is used to generate a database of the expected plastic response and dislocation content evolution associated with several instances of creep loading.From the database, a SM is developed. It relies on the use of orthogonal polynomial regression to describe the evolution of the dislocation content. The SM is then validated against predictions of the dead load creep response given by the polycrystal model across a range of temperatures and stresses. When the SM is used to predict the response of 316H during complex non monotonic loading, extrapolating to new loading conditions, it is found that predictions compare particularly well against those from the physics based polycrystal model.

Three different structures of the evolution equation for the rest stress are derived. They correspond to different models of viscoplastic response, constructed by three-dimensional generalization of simple one-dimensional rheological models. Isotropic, kinematic and combined isotropic-kinematic hardening, with an evolution equation for the back stress, are incorporated in the constitutive framework. The results may be of interest in the analytical and numerical studies of the rate-dependent inelastic response. #
