WebSplit Hopkinson Pressure Bar, also known as Split Hopkinson Pressure bar or Kolsky bar, technique is used to measure the stress-strain response of materials at high strain rates, typically in the range 100-10.000 1/s. The SHPB method can be applied to study the material behavior in compression, tension, and shear. http://splittek.com/
Tension testing in a Split Hopkinson pressure bar (SHPB) is more complex due to a variation of loading methods and specimen attachment to the incident and transmission bar. The first tension bar was designed and tested by Harding et al. in 1960; the design involved using a hollow weight bar that was … See more The split-Hopkinson pressure bar, named after Bertram Hopkinson, sometimes also called a Kolsky bar, is an apparatus for testing the dynamic stress–strain response of materials. See more 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 … See more As with tension testing, there exist a variety of methods for specimen attachment and loading when subjecting materials to torsion on a SHPB.
