Carbon piezoresistive stress gauge
Abstract
The response of the carbon piezoresistive stress gauge was measured in simple and complex shock induced stress fields. The carbon gauge is encapsulated in either a castable epoxy or alumina-filled epoxy and shocked. The gauge response is measured under both gas gun generated, planar shock wave loading and explosive driver generated, divergent shock wave loading. The experimental records are compared to two dimensional, axisymmetric computer calculations of the mean stress and component stresses. There is good agreement between the gauge response and the stress component normal to the plane of the gauge.
