WebThe Split Hopkinson Pressure Bar technique corresponds to a high strain rate deformation of the aluminum alloy at high stress. Figure 1 shows a diagram of the basic Hopkinson bar setup. It consists of two cylindrical bars of the same diameter, respectively called Input and Output bars. Fig 1: Hopkinson bar device. The Hopkinson pressure bar was first suggested by Bertram Hopkinson in 1914 as a way to measure stress pulse propagation in a metal bar. Later, in 1949 Herbert Kolsky refined Hopkinson's technique by using two Hopkinson bars in series, now known as the split-Hopkinson bar, to measure stress and strain, incorporating advancements in the cathode ray oscilloscope in conjunction with electrical condenser units to record the pressure wave propagation in the press…
