Cross-Temperature Defect Identification in Atomistic Simulations via Multi-Level Domain Alignment
Yating Fang, Jungmin Kim, Qian Qian Zhao +4
Identifying atomic defects at elevated temperature is difficult because thermal fluctuations blur the local symmetry that both geometric heuristics and supervised classifiers rely…
E-coherent crystalline interfaces: coherency enhanced by discohesion arrays
Ryan B. Sills, Alejandro Hinojos, Trevor J. Murray +3
Coherent crystalline interfaces form when a pair of joined crystals share lattice sites. Such interfaces are ubiquitous in materials, minerals, and compounds, with examples includi…
Link Statistics of Dislocation Network during Strain Hardening
Sh. Akhondzadeh, Hanfeng Zhai, Wurong Jian +3
Dislocations are line defects in crystals that multiply and self-organize into a complex network during strain hardening. The length of dislocation links, connecting neighboring no…
Length scales and scale-free dynamics of dislocations in dense solid solutions
Gábor Péterffy, Péter D. Ispánovity, Michael E. Foster +2
The fundamental interactions between an edge dislocation and a random solid solution are studied by analyzing dislocation line roughness profiles obtained from molecular dynamics s…
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…
Dislocation Networks and the Microstructural Origin of Strain Hardening
Ryan B. Sills, Nicolas Bertin, Amin Aghaei +1
When metals are plastically deformed, the total density of dislocations increases with strain as the microstructure is continuously refined, leading to the strain hardening behavio…
