A fourth order gauge-invariant gradient plasticity model for polycrystals based on Kröner's incompatibility tensor
Francois Ebobisse, Patrizio Neff
In this paper we derive a novel fourth order gauge-invariant phenomenological model of infinitesimal rate-independent gradient plasticity with isotropic hardening and Kröner's inc…
Existence result for a dislocation based model of single crystal gradient plasticity with isotropic or linear kinematic hardening
Francois Ebobisse, Patrizio Neff, Elias C. Aifantis
We consider a dislocation-based rate-independent model of single crystal gradient plasticity with isotropic or linear kinematic hardening. The model is weakly formulated through th…
Well-posedness for the microcurl model in both single and polycrystal gradient plasticity
Francois Ebobisse, Patrizio Neff, Samuel Forest
We consider the recently introduced microcurl model which is a variant of strain gradient plasticity in which the curl of the plastic distortion is coupled to an additional micromo…
Some properties of the dissipative model of strain-gradient plasticity
C Carstensen, F Ebobisse, AT McBride +2
A theoretical and computational investigation is carried out of a dissipative model of rate-independent strain-gradient plasticity and its regularization. It is shown that the flow…
A canonical rate-independent model of geometrically linear isotropic gradient plasticity with isotropic hardening and plastic spin accounting for the Burgers vector
Francois Ebobisse, Klaus Hackl, Patrizio Neff
In this paper we propose a canonical variational framework for rate-independent phenomenological geometrically linear gradient plasticity with plastic spin. The model combines the…
Existence results in dislocation based rate-independent isotropic gradient plasticity with kinematical hardening and plastic spin: The case with symmetric local backstress
Francois Ebobisse, Patrizio Neff, Daya Reddy
In this paper we use convex analysis and variational inequality methods to establish an existence result for a model of infinitesimal rate-independent gradient plasticity with kine…
