The report contains the preliminary development of a manganin foil stress gage for use in monitoring one dimensional stress waves occurring in axially impacted rods. The results of tests used to calibrate the manganin foil gage to uniform radial strain are presented. These data are used in conjunction with the response of the gage to simultaneously applied axial compression and Poisson straining to find an empirical expression relating the response of the manganin gage to one dimensional stress. Also discussed are limitations on the application of this particular stress transducer. Author
