Abstract
The purpose of this Brief Note is to present experimental stress-time histories along the centerline of impulsively loaded aluminum rods. The measurement is based on the double gauge technique in which we use both a manganin stress gauge and a constantan strain gauge at the same location in the rod. The strain gauge record enables one to eliminate the strain contribution to stress gauge resistance change and have a stress-time history. The measured stress history is compared to a calculated one using two-dimensional Lagrangian code and the agreement between them is good.
