Abstract

This document is a sophomore materials science and engineering tensile testing laboratory handout (Fall 2014) 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 molecular dynamics (MD) simulations, the goal is to help students understand the relationship between macroscopic plastic behavior and the underlying atomic-level mechanisms that involve dislocation motion to facilitate slip along closely-packed planes.

An updated version of the lab (Fall 2015) is available.
