24 Nov 2015 | | Contributor(s):: Aisling Coughlan, Kendra A. Erk, David Ray Johnson, Tanya Faltens, Alejandro Strachan, Heidi A Diefes-Dux
This document is an updated (Fall 2015) sophomore materials science and engineering tensile testing laboratory handout that introduces students to the atomic-level processes that are responsible for plastic deformation. By performing standard tensile tests on a ductile metal in conjunction with...
nanoHUB Materials Simulation Homework: Engineering the Yield Stress of a Material by Controlling Grain Size
26 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...
