Abstract
The purpose of this Brief Note is to demonstrate the feasibility of using commercial manganin stress gauges in dynamic uniaxial stress experiments. This was demonstrated by measuring the stress-time histories inside long aluminum rods that were impacted by rigid wall impactors. The experimental records are compared with a two-dimensional Lagrangian calculation using a recently developed constitutive model (the Phases Model) to describe material behavior.
