Microscopic Calculation of Flow Stress in Cu-Mg Metallic Glass
Nicholas P. Bailey, Jakob Schiøtz, Karsten W. Jacobsen
We have carried out shear-deformation simulations on amorphous Mg-Cu systems at zero temperature and pressure, containing 2048-131072 atoms. At the largest size a smooth stress-str…
Simulation of Cu-Mg metallic glass: Thermodynamics and Structure
Nicholas P. Bailey, Jakob Schiøtz, Karsten W. Jacobsen
We have obtained effective medium theory (EMT) interatomic potential parameters suitable for studying Cu-Mg metallic glasses. We present thermodynamic and structural results from s…
Atomic-scale simulations of nanocrystalline metals
J. Schiøtz, T. Vegge, F. D. Di Tolla +1
Nanocrystalline metals, i.e. metals in which the grain size is in the nanometer range, have a range of technologically interesting properties including increased hardness and yield…
Simulations of mechanics and structure of nanomaterials --- from nanoscale to coarser scales
J. Schiøtz, T. Vegge, F. D. Di Tolla +1
We discuss how simulations of mechanical properties of materials require descriptions at many different length scales --- from the nanoscale where an atomic description is appropri…
