An overview of methods used in dynamic testing of materials [PDF]
Biuletyn Wojskowej Akademii Technicznej, 2023 The paper presents an elemental description and methodology of tests that take intoaccount the effect of high strain rate on materials strength parameters. The article describes suchtesting methodology as: Taylor test, split Hopkinson pressure bar method,

Development of an innovative specimen geometry for tensile split Hopkinson tests [PDF]
EPJ Web of Conferences, 2021 Specimen manufacturing is one of the critical issues to solve during a dynamic material characterization, especially by mean of the Hopkinson bar technique. In particular, concerning tensile testing, the sample is generally axisymmetric with two threaded

Design and Simulation of Insert to Measure Dynamic Sliding Friction in a Split-Hopkinson Pressure Bar [PDF]
EPJ Web of Conferences, 2021 Interfacial friction is a key aspect to understanding and modelling dynamic processes in which materials interact. However, friction is a complex phenomenon that depends on a multitude of factors, including sliding velocity.

Biaxial Compression Tests on Hopkinson Bars [PDF]
The 18th International Conference on Experimental Mechanics, 2018 A biaxial compression Hopkinson bar set-up bas been designed. It consists in a projectile, an input bar and two co-axial output bars. After the projectile impact on the input bar, the internal output bar measures the axial loading of the cross sample whereas the external output bar measures its transversal loading via a mechanism with sliding surfaces.

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 ...

Experiments with the Hopkinson pressure bar [PDF]
Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1923 Abstract In November, 1913, the late Professor Bertram Hopkinson read a paper before the Royal Society entitled “ A method of measuring the Pressure produced in the Detonation of High Explosives or by the Impact of Bullets.” (‘ Phil. Trans.,’ Royal Society of London. Series A, vol. 213 ; and Collected Papers, p. 438.) After this paper

Blast Quantification Using Hopkinson Pressure Bars [PDF]
Journal of Visualized Experiments, 2016 Near-field blast load measurement presents an issue to many sensor types as they must endure very aggressive environments and be able to measure pressures up to many hundreds of megapascals. In this respect the simplicity of the Hopkinson pressure bar has a major advantage in that while the measurement end of the Hopkinson bar can endure and be exposed
