Atomistic simulations of plasticity heterogeneity in gradient nano-grained FCC metals
Materials & Design, 2022 Gradient nano-grained (GNG) metals are an emerging class of heterogeneous structured materials with extraordinary mechanistic performances and unnatural plasticity mechanisms, which are unachievable in traditional homogeneous nanocrystalline metals. Here,

Natural-gradient learning for spiking neurons
eLife, 2022 In many normative theories of synaptic plasticity, weight updates implicitly depend on the chosen parametrization of the weights. This problem relates, for example, to neuronal morphology: synapses which are functionally equivalent in terms of their ...

A Comparison of Plasticity Regularization Approaches for Geodynamic Modeling
Geochemistry, Geophysics, Geosystems, 2023 The emergence, geometry and activation of faults are intrinsically linked to frictional rheology. The latter is thus a central element in geodynamic simulations which aim at modeling the generation and evolution of fault zones and plate boundaries ...

Archives of Mechanics, 2019 In crystal plasticity under prescribed deformation, the incremental material response is potentially non-unique owing to slip system redundancy for most of the crystalline structures.

Burgers tensor flow accounting for cold work and thermal annealing [PDF]
Theoretical and Applied MechanicsThis paper proposes a kinematical-thermal-based constitutive law for the evolution of Burgers tensor during cold work and upon subsequent thermal annealing of a polycrystalline. The proposal is based on the paper by Anand et al. [L. Anand., M. E. Gurtin.,

Enhanced approach to consistency in gradient-dependent plasticity [PDF]
, 2004 This note proposes a modification of gradient-dependent plasticity to improve convergence. In gradient-dependent plasticity, the consistency condition, which results in a differential equation with respect to the plastic multiplier, is solved ...

Archives of Mechanics, 2016 In our previous paper, a simple gradient-enhancement of the classical continuum theory of plasticity of single crystals deformed by multislip has been proposed for incorporating size effects. A single internal length scale has been derived as an explicit

A Concise Review of Gradient Models in Mechanics and Physics
Frontiers in Physics, 2020 The various mathematical models developed over the years to interpret the behavior of materials and corresponding processes they undergo were based on observations and experiments made at that time.
