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...
Atomic Picture of Plastic Deformation in Metals: Lab Assignment Handout
19 Jan 2010 | | Contributor(s):: Alejandro Strachan
In this lab students will perform online molecular dynamics (MD) simulations of metallic nanowires deformed uniaxially and analyze the results...
Atomic Picture of Plastic Deformation in Metals: Overview Lecture
24 Jan 2010 | | Contributor(s):: Alejandro Strachan
The lecture describes the objectives of the learning module and provides the necessary background for the activities. We briefly discuss the following topics:mechanical response of macroscopic polycrystalline metals during tensile tests molecular dynamics simulations of materialsmechanical...
Atomic Picture of Plastic Deformation in Metals: Prelab Lecture
This lecture provides a detailed description of the activities the students will perform in the lab. We present a tutorial with step by step instructions on how to run MD simulations using the nano-Materials Simulation Toolkit.This lecture is part of the learning module Atomic Picture of Plastic...

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...
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...
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.
