An assessment of mechanism-based plasticity models for polycrystalline magnesium alloys
R. Vigneshwaran, Showren Datta, A. A. Benzerga +1
The objective of this work is to assess computationally efficient coarse-grained plasticity models against high-fidelity crystal plasticity simulations for magnesium polycrystals o…
Power-Law Creep from Discrete Dislocation Dynamics
Shyam M. Keralavarma, Tahir Cagin, Tom Arsenlis +1
We report two-dimensional discrete dislocation dynamics simulations of combined dislocation glide and climb leading to `power-law' creep in a model aluminum crystal. The approach f…
Hydrogen Segregation in Palladium and the Combined Effects of Temperature and Defects on Mechanical Properties
Hieu H. Pham, A. Amine Benzerga, Tahir Cagin
Atomistic calculations were carried out to investigate the mechanical properties of Pd crystals as a combined function of structural defects, hydrogen concentration and high temper…
