Twin nucleation in Ti: A study using nudged elastic band (NEB) method
Deepesh Giri, Haitham El Kadiri, Christopher Barrett
Capturing twin nucleation in full-field crystal plasticity is a long-standing problem in materials science. The challenge resides mainly in the biased regional lattice transformati…
LAMMPS Implementation of Rapid Artificial Neural Network Derived Interatomic Potentials
Doyl Dickel, Mashroor Nitol, Christopher Barrett
While machine learning approaches have been successfully used to represent interatomic potentials, their speed has typically lagged behind conventional formalisms. This is often du…
Atomistic simulations of the interaction of basal dislocations with MgZn precipitates in Mg alloys
G. Esteban-Manzanares, R. Alizadeh, I. Papadimitriou +3
The interaction between Mg edge basal dislocations and rod-shaped -MgZn precipitates was studied by atomistic simulations using a new interatomic potential. The atomistic…
The candidacy of shuffle and shear during compound twinning in hexagonal close-packed structures
Haitham El Kadiri, Christopher D. Barrett, Mark A. Tschopp
This paper proposes a systematic generalized formulation for calculating both atomic shuffling and shear candidates for a given compound twinning mode in hexagonal closed-packed me…
