Using the split Hopkinson pressure bar to validate material models. [PDF]
Philos Trans A Math Phys Eng Sci, 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.

Electromagnetic Interference in Measurements of Radial Stress During Split Hopkinson Pressure Bar Experiments. [PDF]
Exp Mech, 2017 Split Hopkinson pressure bar experiments on soils are often carried out using a rigid steel confining ring to provide plane strain conditions, and measurements of the circumferential strain in the ring can be used to infer the radial stress on the ...

Design of a split Hopkinson pressure bar with partial lateral confinement [PDF]
Measurement Science and Technology, 2016 This paper presents the design of a modified split Hopkinson pressure bar (SHPB) where partial lateral con- finement of the specimen is provided by the inertia of a fluid annulus contained in a long steel reservoir.

Dynamic tensile strength enhancement of concrete in split Hopkinson pressure bar test
Advances in Mechanical Engineering, 2018 Split Hopkinson pressure bar technique has been widely used to measure the dynamic tensile strength of concrete materials. Most experimental results show that the tensile strength of concrete material increases with strain rates.

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 ...
