Publication: Automated Hopkinson Bar Device for low frequency fatigue testing

IMPACT group has developed a fully automatized Split Hopkinson Bar setup for low cycle impact fatigue studies. The system consists of a classical SHB setup with automatized rapid resetting of the striker, bars, and the specimen at a rate of one impact in every 2 seconds. The developed technique thus allows for impact fatigue studies to be carried out with feasible human effort and within practical time spans while maintaining the excellent control and measurement capabilities inherent to the SHB technique.
