Glassy features of crystal plasticity [PDF]
, 2016 Crystal plasticity occurs by deformation bursts due to the avalanche-like motion of dislocations. Here we perform extensive numerical simulations of a three-dimensional dislocation dynamics model under quasistatic stress-controlled loading.

Anisotropic shock response of columnar nanocrystalline Cu [PDF]
, 2010 We perform molecular dynamics simulations to investigate the shock response of idealized hexagonal columnar nanocrystalline Cu, including plasticity, local shear, and spall damage during dynamic compression, release, and tension.

Plastic-embedded protein crystals [PDF]
Journal of Synchrotron Radiation, 2006 Rapid vitrification followed by the replacement of the vitrified water by a solvent (freeze substitution) and then resin is a widely used procedure for preparing biological samples for electron microscopy. The resulting plastic-embedded samples permit convenient room-temperature sectioning (microtomy) and can yield well preserved cellular structures ...

Micromechanical investigation of the influence of defects in high cycle fatigue [PDF]
, 2014 This study aims to analyse the influence of geometrical defects (notches and holes) on the high cycle fatigue behaviour of an electrolytic copper based on finite element simulations of 2D polycrystalline aggregates.

Forming of Magnesium — Crystal Plasticity and Plastic Potentials [PDF]
AIP Conference Proceedings, 2007 Hexagonal close‐packed (hcp) metals show a deformation behavior, which is quite different from that of materials with cubic crystalline structure. As a consequence, rolled or extruded products of magnesium and its alloys exhibit a strong anisotropy and an unlike yielding in tension and compression.

Computational Modeling of Dislocation Slip Mechanisms in Crystal Plasticity: A Short Review
Crystals, 2021 The bridge between classical continuum plasticity and crystal plasticity is becoming narrower with continuously improved computational power and with engineers’ desire to obtain more information and better accuracy from their simulations, incorporating ...

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
