HOMOGENIZATION IN GRADIENT PLASTICITY
Mathematical Models and Methods in Applied Sciences, 2011 This paper yields a two-scale homogenization result for a rate-independent elasto-plastic system. The presented model is a generalization of the classical model of linearized elasto-plasticity with hardening, which is extended by a gradient term of the plastic variables.

Gradient Plasticity for Single Crystals [PDF]
PAMM, 2010 AbstractThe kinematic relationship between classical single crystal kinematics and geometrically necessary dislocations will be clarified by a demonstrative example. The starting point for the dynamics is the contribution of geometrically necessary dislocations to the free energy, which leads to a kinematic hardening law. A simple two‐dimensional shear

Meta-SpikePropamine: learning to learn with synaptic plasticity in spiking neural networks
Frontiers in Neuroscience, 2023 We propose that in order to harness our understanding of neuroscience toward machine learning, we must first have powerful tools for training brain-like models of learning.

Ductilizing Al-Mn strips via gradient texture
Materials Research Letters, 2023 Improved strength-ductility synergy is not uncommon among metallic materials with gradient structures of grains and twins. In this work, we report that the texture gradient innately created in Al-Mn strips by twin-roll casting is also capable of ...

Fracture in distortion gradient plasticity [PDF]
International Journal of Engineering Science, 2020 In this work, distortion gradient plasticity is used to gain insight into material deformation ahead of a crack tip. This also constitutes the first fracture mechanics analysis of gradient plasticity theories adopting Nye's tensor as primal kinematic variable. First, the asymptotic nature of crack tip fields is analytically investigated.
