Research data supporting: "Application of photon Doppler velocimetry to direct impact Hopkinson pressure bars"

The stress strain relationships of a variety of materials measured with and without photon Doppler based velocity measurements in a direct impact Hopkinson bar system. Also included are equivalent tests in a split Hokinson pressure bar system as a benchmark for the two methods. Collected in January 2015. Also included are spectra from several experiments to allow the user to practice and develop a Fourier (or otherwise based) PDV analysis routine. Notably the spectrum from the inset in Figure 4 which was also has a complimentary velocity trace in the figure, and was the first experiment performed using this method with a sample in the system. This experiment was performed on 26/06/2014
