Assessment of a two-surface plasticity model for hexagonal materials
Journal of Magnesium and Alloys, 2023 A computationally efficient two-surface plasticity model is assessed against crystal plasticity. Focus is laid on the mechanical behavior of magnesium alloys in the presence of ductility-limiting defects, such as voids.

Intermittency in crystal plasticity informed by lattice symmetry [PDF]
, 2015 We develop a nonlinear, three-dimensional phase field model for crystal plasticity which accounts for the infinite and discrete symmetry group G of the underlying periodic lattice.

International Journal of Fracture, 2021 In the present study, a hypoelastic–plastic formulation of porous crystal plasticity with a regularized version of Schmid’s law is proposed. The equation describing the effect of the voids on plasticity is modified to allow for an explicit analytical ...

Plasticity without phenomenology: a first step
, 2020 A novel, concurrent multiscale approach to meso/macroscale plasticity is demonstrated. It utilizes a carefully designed coupling of a partial differential equation (pde) based theory of dislocation mediated crystal plasticity with time-averaged inputs ...

A Crystal Plasticity Investigation of Grain Size-Texture Interaction in Magnesium Alloys
Acta Materialia, 2021 This work investigates the microstructure-property linkages in magnesium (Mg) with an emphasis on understanding interaction effects between the grain size, texture, and loading orientation.

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

Plastic avalanches in metal-organic framework crystals [PDF]
arXiv, 2023 The compressive properties of metal-organic framework (MOF) crystals are not only crucial for their densification but also key in determining their performance in many applications. We herein investigated the mechanical responses of a classic crystalline MOF, HKUST-1 by using in situ compression tests.

Plasticity of Bismuth Crystals [PDF]
Nature, 1936 MUCH evidence of a conflicting nature has been advanced on the subject of the plasticity of bismuth: the following brief account of some new experiments may therefore be of interest.
