The model is an extension of a rate-independent version, and includes a new hardening relation that has recently been proposed in the small-deformation context (Gurtin and Reddy, 2014), and which accounts for slip-system interactions due to self and latent hardening. Energetic and dissipative effects, each with its corresponding length scale, are included. Numerical results are presented for a single crystal with single and multiple slip systems, as well as an ensemble of grains. These results provide a clear illustration of the effects of accounting for slip-system interactions.en0020-7683201415-1627542764ElsevierInteractive hardening relationLatent hardeningPolycrystalSingle-crystal strain-gradient viscoplasticityInformatikNaturwissenschaftenPhysikChemieJournal Article10.1016/j.ijsolstr.2014.03.010Journal Article
