Finite element simulation of strain localization in inelastic solids by energy relaxation
Vietnam Journal of Mechanics, 2011 A new approach for the treatment of strain localization in inelastic material is proposed. It is based on energy minimization principles associated with micro-structure developments. Shear bands are treated as micro-shearing of rank-one laminates. It is

Migration and Localization of Metal Atoms on Strained Graphene [PDF]
Physical Review Letters, 2010 Reconstructed point defects in graphene are created by electron irradiation and annealing. By applying electron microscopy and density functional theory, it is shown that the strain field around these defects reaches far into the unperturbed hexagonal network and that metal atoms have a high affinity to the nonperfect and strained regions of graphene ...

On the application of strain gradient crystal plasticity to study strain localization phenomena in single crystals [PDF]
, 2021 Strain localization is an important plastic instability process occurring prior to fracture. It is usually observed in the form of narrow bands of intense plastic shear strain in deformed bodies undergoing severe inhomogeneous deformation.

Fracture and Structural Integrity, 2022 Strain localization is one of the key phenomena which has been extensively studied in geomaterials and for other kinds of materials including metals and polymers. This well-known phenomenon appears when structure/material is closed to failure.

Ellipticity loss analysis for tangent moduli deduced from a large strain elastic–plastic self-consistent model [PDF]
, 2009 In order to investigate the impact of microstructures and deformation mechanisms on the ductility of materials, the criterion first proposed by Rice is applied to elastic–plastic tangent moduli derived from a large strain micromechanical model combined ...

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 ...

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 ...

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 ...
