A measurement of wave propagation in the split Hopkinson pressure bar
Measurement Science and Technology, 2009 This paper presents results from optical and analytical measurements of stress wave propagation in a rod of PMMA. The rod is loaded between the incident and transmitter bars of a split Hopkinson pressure bar. Displacements in the rod are measured using high speed photography with digital image correlation.
