Cooperativity in plastic crystals
Physical Review E, 2018 A statistical mechanical model previously adopted for the analysis of the α-relaxation in structural glass formers is rederived within a general theoretical framework originally developed for systems approaching the ideal glassy state. The interplay between nonexponentiality and cooperativity is reconsidered in the light of energy landscape concepts ...

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.

Phase-field modelling of fracture in single crystal plasticity [PDF]
, 2016 We propose a phase-field model for ductile fracture in a single crystal within the kinematically linear regime, by combining the theory of single crystal plasticity as formulated in Gurtin et al.

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.

Nanoscale mosaicity revealed in peptide microcrystals by scanning electron nanodiffraction. [PDF]
, 2019 Changes in lattice structure across sub-regions of protein crystals are challenging to assess when relying on whole crystal measurements. Because of this difficulty, macromolecular structure determination from protein micro and nanocrystals requires ...

Investigation into the Effects of Prior Plasticity on Creep Accumulation in 316H Stainless Steel
Physical Sciences Forum, 2022 Steel components in the boilers of nuclear reactors are subject to high temperatures and varying loading conditions. This can introduce time-dependent and time-independent plasticity, which can interact with one another.

Statistical approach to dislocation dynamics: From dislocation correlations to a multiple-slip continuum plasticity theory [PDF]
, 2007 Due to recent successes of a statistical-based nonlocal continuum crystal plasticity theory for single-glide in explaining various aspects such as dislocation patterning and size-dependent plasticity, several attempts have been made to extend the theory ...
