A method to extract slip system dependent information for crystal plasticity models

MethodsX, 2022
A tool to implement a length scale dependency to classical crystal plasticity simulations is presented. Classical crystal plasticity models do not include a size effect; therefore, the size of the grain does not influence the simulated deformation ...

Modeling the zonal disintegration of rocks near deep level tunnels by gradient internal variable continuous phase transition theory

Journal of the Mechanical Behavior of Materials, 2015
The occurrence of alternating damage zones surrounding underground openings (commonly known as zonal disintegration) is treated as a “far from thermodynamic equilibrium” dynamical process or a nonlinear continuous phase transition phenomenon.

A minimal gradient-enhancement of the classical continuum theory of crystal plasticity. Part I: The hardening law

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.

Coordinated optimization of visual cortical maps (II) Numerical studies [PDF]

, 2012
It is an attractive hypothesis that the spatial structure of visual cortical architecture can be explained by the coordinated optimization of multiple visual cortical maps representing orientation preference (OP), ocular dominance (OD), spatial frequency,

Non-local fractional model of rate independent plasticity [PDF]

, 2013
In the paper the generalisation of classical rate independent plasticity using fractional calculus is presented. This new formulation is non-local due to properties of applied fractional differential operator during definition of kinematics.

Study of size effects in thin films by means of a crystal plasticity theory based on DiFT [PDF]

, 2007
In a recent publication, we derived the mesoscale continuum theory of plasticity for multiple-slip systems of parallel edge dislocations, motivated by the statistical-based nonlocal continuum crystal plasticity theory for single-glide due to Yefimov et ...
