Strain Localisation and Fracture of Nuclear Reactor Core Materials
Journal of Nuclear Engineering, 2023 The production of prismatic dislocation loops in nuclear reactor core materials results in hardening because the loops impede dislocation motion. Yielding often occurs by a localised clearing of the loops through interactions with gliding dislocations ...

A thermodynamically consistent plastic-damage framework for localized failure in quasi-brittle solids: material model and strain localization analysis [PDF]
, 2016 Aiming for the modeling of localized failure in quasi-brittle solids, this paper addresses a thermodynamically consistent plastic-damage framework and the corresponding strain localization analysis. A unified elastoplastic damage model is first presented

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 ...

Emergence of Shear Bands in Confined Granular Systems: Singularity of the q-Statistics
Entropy, 2018 The statistics of grain displacements probability distribution function (pdf) during the shear of a granular medium displays an unusual dependence with the shear increment upscaling as recently evinced (see “experimental validation of a ...

Strain localization and anisotropic correlations in a mesoscopic model of amorphous plasticity [PDF]
, 2007 A mesoscopic model for shear plasticity of amorphous materials in two dimensions is introduced, and studied through numerical simulations in order to elucidate the macroscopic (large scale) mechanical behavior.

Strain localization in a shear transformation zone model for amorphous solids
, 2007 We model a sheared disordered solid using the theory of Shear Transformation Zones (STZs). In this mean-field continuum model the density of zones is governed by an effective temperature that approaches a steady state value as energy is dissipated.
