A tensile split Hopkinson pressure bar for low impedance materials [PDF]
AIP Conference Proceedings, 2020 A split Hopkinson pressure bar that is specifically designed for testing low impedance materials in uniaxial tension is discussed. The input and output bars are each 2.1 m long and formed of titanium alloy tubes and are of low mechanical impedance (Grade 9 alloy, 16 mm outside diameter, 1mm wall thickness). Tensile pulses are generated by the action of

One-dimensional dynamic compressive behavior of dry calcareous sand at high strain rates
Journal of Rock Mechanics and Geotechnical Engineering, 2019 Calcareous sand has distinct characteristics in comparison with silica sand, such as dynamic behavior at high strain rates (HSRs). This is closely related to pile driving, aircraft wheel loading and mining activities.

Electromagnetic Compressive Split Hopkinson Bar [PDF]
This paper proposes a new design for the compressive split Hopkinson bar that makes use of the intense pressure created in a transient magnetic field formed by the passage of a pulse of electric current through a series of coils.

Experimental study of the high strain rate shear behaviour of Ti6Al4V [PDF]
, 2011 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 ...

Texture Evolution of AZ31 Magnesium Alloy Sheet at High Strain Rates [PDF]
, 2010 In the current contribution the mechanical behaviour at high strain rates of AZ31 magnesium alloy sheet is studied. Uniaxial deformation properties were studied by means of tensile split Hopkinson pressure bar (SHPB) at different temperatures.
