Journal ArticleDOI
Overview of constitutive laws, kinematics, homogenization and multiscale methods in crystal plasticity finite-element modeling: Theory, experiments, applications
TL;DR: In this paper, a review of continuum-based variational formulations for describing the elastic-plastic deformation of anisotropic heterogeneous crystalline matter is presented and compared with experiments.
Journal ArticleDOI
Softening of nanocrystalline metals at very small grain sizes
TL;DR: In this paper, the deformation of nanocrystalline copper has been studied and it is shown that the hardness and yield stress of the material typically increase with decreasing grain size, a phenomenon known as the reverse Hall-Petch effect.
Journal ArticleDOI
Plasticity in small-sized metallic systems: Intrinsic versus extrinsic size effect
TL;DR: In this paper, the authors provide an overview of metal-based material classes whose properties as a function of external size have been investigated and provide a critical discussion on the combined effects of intrinsic and extrinsic sizes on the material deformation behavior.
Book ChapterDOI
Micromechanics of Crystals and Polycrystals
TL;DR: In this paper, Hill's analysis of the mechanics of elastic-plastic crystals is extended by incorporating the possibility of deviations from the Schmid rule of a critical resolved shear stress for slip.

Dislocation nucleation governed softening and maximum strength in nano-twinned metals
TL;DR: It is shown that dislocation nucleation governs the strength of nano-twinned materials, resulting in their softening below a critical twin thickness, and the critical twin-boundary spacing and the maximum strength depend on the grain size.
