A mechanism-based theory of strain gradient plasticity (MSG) is proposed based on a
multiscale framework linking the microscale notion of statistically stored and geometrically …

In the finite-deformation, continuum theory of crystal plasticity, the lattice is assumed to
distort only elastically, while generally the elastic deformation itself is not compatible with a …

In this work, a gradient-and rate-dependent crystallographic formulation is proposed to
investigate the macroscopic behaviour of two-phase single crystals. The slip-system-based …

This work deals with the prediction of grain-size dependent hardening in FCC and BCC
polycrystalline metals at moderately high strains (2–30%). The model considers 3–D …

A Phenomenological Mesoscopic Field Dislocation Mechanics (PMFDM) model is
developed, extending continuum plasticity theory for studying initial-boundary value …

This work extends the constitutive model for the prediction of grain-size dependent
hardening in fcc polycrystalline metals proposed by Acharya and Beaudoin [1](Grain-size …

A new hardening law of the strain gradient theory is proposed in this paper, which retains
the essential structure of the incremental version of conventional J2 deformation theory and …

Large strain gradients exist near the tip of a crack due to stress singularity. The strain-
gradient effect becomes significant when the size of the fracture process zone around a …

We present a framework which unifies classical phenomenological J 2 and crystal plasticity
theories with quantitative dislocation mechanics. The theory allows the computation of stress …

The near-tip asymptotic field and full-field solution are obtained for a mode III crack in an
elastic material with strain gradient effects. The asymptotic analysis shows that, even though …
