An analytic model of the evolution of dislocation density in fcc polycrystals is described. The
evolution equations approximately account for most known dislocation storage, dynamic …

The cross-correlation based HR-EBSD technique was used to derive stored geometrically
necessary dislocation (GND) density in the OFHC copper samples deformed under uniaxial …

A model is presented in condensed form for the strain hardening of fcc crystals. It is based
on a version of the storage–recovery frame in terms of average dislocation densities per slip …

A unified physically based crystal plasticity model for FCC crystalline materials is developed.
This statistical dislocation dynamics based model considers the cellular dislocation …

A two state variable hardening law is developed that is capable of simulating stage IV
hardening. It is based on a physically motivated dislocation density evolution equation …

The present TEM study on deformed copper single crystals had several objectives. In a first
step, the line tensions of near-edge and near-screw dislocations were determined directly by …

Single crystals of copper and nickel were plastically deformed at room temperature into
stage III of the work hardening curve and by creep at 0.4 T m (melting temperature). The …

Discrete dislocation dynamics simulations are carried out to systematically investigate the
rate dependent deformation behaviour of polycrystalline bulk copper by varying the loading …

While the grain size effect (GSE) is universally observed in polycrystalline metals and alloys,
extended dislocation pileups (DPUs) at grain boundaries (GBs) are rarely observed …

Dislocation density-based evolution formulations that are related to a heterogeneous
microstructure and are physically representative of different crystalline interactions have …
