Advancements in the Split Hopkinson Bar Test
The split Hopkinson bar test is the most commonly used method for determining material properties at high rates of strain. The theory governing the specifics of Hopkinson bar testing has been around for decades. It has only been the last decade or so, however, that significant data processing …

Experimental determination of material properties for materials subjected to high compressive strain rates
The design, fabrication and operation of a split Hopkinson bar apparatus is described. The theoretical basis for the experimental determination of material properties for materials subjected to high compressive strain rates using the split Hopkinson bar is discussed along with the assumptions made …

Extending the annular in-plane torsional shear test specimen to applications at high strain rates
… tests were performed on a modified torsional split Hopkinson bar (TSHB) system. The TSHB system adopted a nested configuration which allowed for a longer incident bar, and thus larger obtainable strains. Two quick-release mechanisms were used, one using a novel reusable wedge and the other …

An experimental investigation of interspecies variation in mechanical properties of cortical bone
… higher rate tests were performed on a modified Split Hopkinson bar setup. A Cone-in-Tube striker was used to provide a near constant strain rate during testing. The use of a momentum trapping system was investigated, but was not practically useful for the scale of specimens and strain rates …

Degradation behaviour of the mechanical properties of bovine cortical bone
… strain rate tests using a three-point bending split Hopkinson bar yield rich datasets, indicating clear trends applicable for numerical validation. Simulations utilizing dynamic compression and cross-section data exhibit encouraging correlations with experimental observations. A comparison …

Bruchverhalten von Leichtmetallen unter Impact-Beanspruchung
In the context of this research work, the flow and fracture behaviour of the Al alloy AA7075 (AlZnMgCu1.5), the Mg alloy AZ80 (MgAl8Zn) and the Ti alloy TiAl6V4 have been investigated in compression and tensile tests at different strain rates (0.001-5000s-1) und temperatures (20-450°C). To evaluate …
