Nanoscale Tensile Testing with Molecular Dynamics
21 Feb 2019 | | Contributor(s):: Sam Reeve, Alejandro Strachan
In this computational lab you will perform online molecular dynamics (MD) simulations through nanoHUB of single-crystal copper nanowires under uniaxial tension of varying orientations and analyze the results in order to: Observe how slip planes in single-crystal nanowires are formed and...

Plastic Deformation at the Nanoscale
28 Aug 2015 | | Contributor(s):: Marisol Koslowski
To model the deformation of metallic materials at micron and submicron scales a continuum theory of dislocations is derived. We will introduce the MicroMechanics Simulation Tool and the NanoPlasticity Lab. Both tools are dislocation mechanics simulations for the prediction of plastic deformation...
