Nano-micro scale transition through atomistic continuum coupling via homogenization
Atomistic computer simulations based on classical interatomic potentials allow the description of material properties and processes with high temporal and spatial resolution but are limited to small system sizes ...

Atomistic modeling of severe plastic deformation at the nanoscale
Background: Severe plastic deformation (SPD) processes are forming techniques that impose large plastic strains to achieve ultra-fine grained and nanocrystalline microstructures. The refined microstructure results in a significant increase in strength ...
