Nontrivial scaling exponents of dislocation avalanches in microplasticity

G Sparks, R Maaß - Physical Review Materials, 2018 - APS
Crystal plasticity causes structural fluctuations that can be scale-free and therefore admit
power-law distributions. Numerous experiments, modeling, and theory have reported a …

Landau-type theory of planar crystal plasticity

R Baggio, E Arbib, P Biscari, S Conti, L Truskinovsky… - Physical Review Letters, 2019 - APS
We show that nonlinear continuum elasticity can be effective in modeling plastic flows in
crystals if it is viewed as a Landau theory with an infinite number of equivalent energy wells …

Discontinuous yielding of pristine micro-crystals

OU Salman, R Baggio… - Comptes …, 2021 - comptes-rendus.academie-sciences …
We study the mechanical response of a dislocation-free 2D crystal under homogenous
shear using a new mesoscopic approach to crystal plasticity, a Landau-type theory …

Glassy features of crystal plasticity

A Lehtinen, G Costantini, MJ Alava, S Zapperi… - Physical Review B, 2016 - APS
Crystal plasticity occurs by deformation bursts due to the avalanchelike motion of
dislocations. Here we perform extensive numerical simulations of a three-dimensional …

Inelastic rotations and pseudoturbulent plastic avalanches in crystals

R Baggio, OU Salman, L Truskinovsky - Physical Review E, 2023 - APS
Plastic deformations in crystals produce microstructures with randomly oriented patches of
unstressed lattice forming complex textures. We use a mesoscopic Landau-type tensorial …

Avalanches and rate effects in strain-controlled discrete dislocation plasticity of Al single crystals

D Kurunczi-Papp, L Laurson - Physical Review Materials, 2023 - APS
Three-dimensional discrete dislocation dynamics simulations are used to study strain-
controlled plastic deformation of face-centered cubic aluminium single crystals. After …

Ericksen-Landau Modular Strain Energies for Reconstructive Phase Transformations in 2D Crystals

E Arbib, P Biscari, C Patriarca, G Zanzotto - Journal of Elasticity, 2024 - Springer
