Absence of off-diagonal long-range order in hcp He dislocation cores

Maurice de Koning, Wei Cai, Claudio Cazorla +1

The mass transport properties along dislocation cores in hcp He are revisited by considering two types of edge dislocations as well as a screw dislocation, using a fully correl…

Dislocation Density-Based Plasticity Model from Massive Discrete Dislocation Dynamics Database

Sh. Akhondzadeh, Ryan B. Sills, Nicolas Bertin +1

We present a dislocation density-based strain hardening model for single crystal copper through a systematic coarse-graining analysis of more than 200 discrete dislocation dynamics…
