SPLITTEK - Dynamic Engineering Test
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 … Meer weergeven 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. Meer weergeven 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 … Meer weergeven For compression testing, two symmetrical bars are situated in series, with the sample in between. The incident bar is struck by a striker bar during testing. The striker bar is fired from a … Meer weergeven • List of historic mechanical engineering landmarks Meer weergeven Although there are various setups and techniques currently in use for the split-Hopkinson pressure bar, the underlying principles for the test and measurement are the … Meer weergeven As with tension testing, there exist a variety of methods for specimen attachment and loading when subjecting materials to torsion on a SHPB.
