Abstract Chemical heterogeneities along grain boundaries in garnet occur across a wide range of metamorphic conditions, yet the processes underlying their development remain poorly understood. Here we integrate electron backscattered diffraction (EBSD) and atom probe tomography (APT) to evaluate mechanisms driving nanoscale trace element mobility deformation microstructures granulite-facies gar...

A crystal plasticity-based constitutive model is developed to describe the thermomechanical behavior of pseudoelastic NiTi single crystal. The includes, for first time in literature, all inelastic mechanisms influencing fatigue SMAs a finite strain framework: martensite transformation, deformation slip austenite at high-temperature, twinning large strain, transformation-induced plasticity (TRIP...

This paper presents the first application of peridynamics theory for crystal plasticity simulations. A statebased theory of peridynamics is used (Silling et al., 2007) where the forces in the bonds between particles are computed from stress tensors obtained from crystal plasticity. The stress tensor at a particle, in turn, is computed from strains calculated by tracking the motion of surroundin...

Power law fluctuations and scale-free spatial patterns are known to characterize steady state plastic flow in crystalline materials. In this Letter we study the emergence of correlations in a simple Frenkel-Kontorova-type model of 2D plasticity which is largely free of arbitrariness, amenable to analytical study, and is capable of generating critical exponents matching experiments. Our main obs...

The properties and behaviour of an  colony Ti-6242 alloy have been investigated at 20C utilising coupled micro-pillar stress relaxation tests and computational crystal plasticity. The -phase slip strength and intrinsic slip system strain rate sensitivity have been determined, and the -phase shown to have stronger rate sensitivity than that for the  phase. Close agreement of experimental o...
