Fluctuation phenomena in crystal plasticity - a continuum model [PDF]
, 2005 On microscopic and mesoscopic scales, plastic flow of crystals is characterized by large intrinsic fluctuations. Deformation by crystallographic slip occurs in a sequence of intermittent bursts ('slip avalanches') with power-law size distribution. In the

Archives of Mechanics, 2016 A simple gradient-enhancement of the classical continuum theory of plasticity of single crystals deformed by multislip is proposed for incorporating size effects in a manner consistent with phenomenological laws established in materials science.

Reward-optimizing learning using stochastic release plasticity. [PDF]
Front Neural CircuitsSynaptic plasticity underlies adaptive learning in neural systems, offering a biologically plausible framework for reward-driven learning. However, a question remains: how can plasticity rules achieve robustness and effectiveness comparable to error ...

Strain gradient plasticity: energetic or dissipative? [PDF]
, 2015 It has been established by computation, and confirmed by analysis, for an infinite slab of strain-gradient sensitive material subjected to plane-strain tensile loading, that passivation of the lateral boundaries at some stage of loading inhibits plastic ...

Mode I crack tip fields: strain gradient plasticity theory versus J2 flow theory
, 2019 The mode I crack tip asymptotic response of a solid characterised by strain gradient plasticity is investigated. It is found that elastic strains dominate plastic strains near the crack tip, and thus the Cauchy stress and the strain state are given ...

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.
