The Use of Manganin Stress Transducers in Impulsively Loaded Long Rod Experiments

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.
