Atomistic Finite Deformation Simulations: A Discussion on Length Scale Effects in Relation to Mechanical Stresses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, atomistic finite deformation calculations employing the Embedded Atom Method show three items of interest related to continuum field theory. First, a spatial size scale effect on ...
Interpretations of Indentation Size Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For very shallow indentations in W, Al, Au, and Fe-3wt%Si single crystals, hardness decreased with increasing depth irrespective of increasing or decreasing strain gradients. As such, strain ...
Torsion/Simple Shear of Single Crystal Copper
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We analyze simple shear and torsion of single crystal copper by employing experiments, molecular dynamics simulations, and finite element simulations in order to focus on the kinematic responses ...
Semi-Empirical Potential Methods for Atomistic Simulations of Metals and Their Construction Procedures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: General theory of semi-empirical potential methods including embedded-atom method and modified-embedded-atom method (MEAM) is reviewed. The procedures to construct these potentials are also reviewed. ...
