  1. Atomic Picture of Plastic Deformation in Metals via Online Molecular Dynamics Simulations

    01 Jun 2011 | | Contributor(s):: Alejandro Strachan

    The main goal of this learning module is to introduce students to the atomic-level processes responsible for plastic deformation in crystalline metals and help them develop a more intuitive understanding of how materials work at molecular scales. The module consists of: i) Two introductory...

  11. 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...

  12. Reproducing results from "PUQ: a code for non-intrusive uncertainty propagation in computer simulations"

    27 Mar 2015 | | Contributor(s):: Martin Hunt, Marisol Koslowski, Alejandro Strachan

    In this document we use the nanoPLASTICITY in nanoHUB to reproduce results of the paper "PUQ: a code for non-intrusive uncertainty propagation in computer simulations" to be published in Computer Physics Communications. The paper abstract follows. We present a software package for the...

  14. Understanding Powder Compaction Using Single Particle Measurements (an experimental approach)

    27 Jul 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.
