Webtest specimen, lower in strength than the bars, experienced plas-tic deformation. Both the stress and strain could be derived. This modification became know as the Split-Hopkinson Pressure Bar. Hopkinson and Kolsky used explosive pellets to generate the stress pulse that propagated along the bar. In the early 1960s, Ulric Lindholm of SwRI ... WebSplit Hopkinson Pressure Bar The Properties A split Hopkinson pressure bar (SHPB), is a test apparatus used to characterize the mechanical response of materials deforming at high strain rates (102 – 104 s-1).
WebThe Split-Hopkinson-Pressure-Bar system can operate in compression and tension and allows for testing of materials at the magnitude of strain rates seen when a bullet strikes … 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.
Webcompression was calculated as the area under the stress-strain curve. The dynamic behavior of the composite was investigated using the split Hopkinson pressure bar technique. It was found that ceramic-elastomer composites effectively dissipate the energy. Moreover, a ballistic test was carried out using armor piercing bullets.
