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...

Homework assignment: learning about elastic constants via molecular dynamics simulations
17 Feb 2015 | | Contributor(s):: Alejandro Strachan, David Ray Johnson
In this homework assignment students will use molecular dynamics to compute the elastic constants of metals using an embedded atom model to describe atomic interactions. They will deform a single crystal along different directions and obtain c11, c12 and c44 elastic constants from the...
nanoHUB Materials Simulation Homework: Engineering the Yield Stress of a Material
17 Feb 2015 | | Contributor(s):: Marisol Koslowski, Tanya Faltens
This homework assignment uses the nanoplasticity lab simulation tool to enable students to explore how grain size and the competing plastic deformation mechanisms of dislocation motion and grain boundary sliding affect the yield stress of a sample. Students create conditions that lead to...
Mechanical Behavior of MEMS/NEMS
25 Feb 2014 | | Contributor(s):: Yong Zhu
This lecture covers mechanical testing methods and behaviors of thin films and nanostructures. This lecture is related to the activities at the NSF Nanosystems Engineering Research Center (NERC) for Advanced Self-Powered Systems of Integrated Sensors and Technologies (ASSIST) at NC State University.
