Numerical Simulation for Bar Straightness Effect in Split Hopkinson Pressure Bar
Procedia Engineering, 2017 Abstract Bars alignment in a Split Hopkinson Pressure Bar influences the quality of signal recorded during experiments, and thus affects the data of material properties being measured. There are some parameters directly related to the bars alignment such as their straightness, the impact face parallelism, and the neutral axis offset.

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract During an earthquake a dynamic rupture propagates, causing fractures and permanent damage that modify the mechanical properties of the fault and its surroundings. Reciprocally, the energy dissipated by the mechanical transformation of the fault rock has a direct feedback on the dynamics of the seismic rupture.

A measurement of wave propagation in the split Hopkinson pressure bar
Measurement Science and Technology, 2009 This paper presents results from optical and analytical measurements of stress wave propagation in a rod of PMMA. The rod is loaded between the incident and transmitter bars of a split Hopkinson pressure bar. Displacements in the rod are measured using high speed photography with digital image correlation.

Modified Split Hopkinson Pressure Bar for the investigations of dynamic behaviour of magnetorheological materials [PDF]
, 2018 The magnetorheological fluid is a functional material that is changing its rheological properties and finally solidifies in a magnetic field. The dynamic behaviour, tested with the use of the Split Hopkinson Pressure Bar is an important issue for ...
