Using the split Hopkinson pressure bar to validate material models [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 This paper gives a discussion of the use of the split-Hopkinson bar with particular reference to the requirements of materials modelling at QinetiQ. This is to deploy validated material models for numerical simulations that are physically based and have as little characterization overhead as possible.

Dynamic rock tests using split Hopkinson (Kolsky) bar system – A review
Journal of Rock Mechanics and Geotechnical Engineering, 2015 Dynamic properties of rocks are important in a variety of rock mechanics and rock engineering problems. Due to the transient nature of the loading, dynamic tests of rock materials are very different from and much more challenging than their static ...

The split Hopkinson bar bulge setup: a novel dynamic biaxial test method [PDF]
EPJ Web of Conferences, 2021 In sheet metal forming, very often, large plastic deformations are imposed to a thin plate. An accurate description of the material’s elastoplastic response is therefore of paramount importance to perform finite element (FE) simulations of an actual ...
