Blast Quantification Using Hopkinson Pressure Bars [PDF]
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

A Review of the Torsional Split Hopkinson Bar [PDF]
Mechanical behavior of materials at medium and high strain rates (101ā¼104āsā1) is the foundation of developing mechanical theories, building material models, and promoting engineering design and construction. The torsional split Hopkinson bar (TSHB) is an effective experimental technique for measuring the pure shear mechanical properties of materials ...

Experimental study of the high strain rate shear behaviour of Ti6Al4V [PDF]
Three different high strain rate shear test techniques are applied on the titanium alloy Ti6Al4V. Two techniques for testing of bulk materials and one technique for sheet materials are used: torsion of thin-walled tubes, compression of hat-shaped ...

Two-wave photon Doppler velocimetry measurements in direct impact Hopkinson pressure bar experiments
Direct impact Hopkinson pressure bar systems offer many potential advantages over split Hopkinson pressure bars, including access to higher strain rates, higher strains for equivalent striker velocity and system length, lower dispersion and faster ...
