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...

Understanding Powder Compaction Using Single Particle Measurements (an experimental approach)
07 Aug 2017 | | Contributor(s):: Felix D Monge, Marcial Gonzalez, Ankit Agarwal
Many macroscopic materials are made (or can only be made) with small particles. Therefore, a fundamental understanding of their microstructures and behavior when compacted is necessary to advance our models and industry.

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...
