For a valid split Hopkinson pressure bar (SHPB) or Kolsky compression bar experiment, the sample should be in dynamic stress equilibrium over most of the test duration. In this study, we investigate the effect of radial inertia on elastic samples during a valid SHPB test. We present closed-form equa
The potential error due to friction in compression split Hopkinson pressure bar (SHPB) tests is assessed and conditions for minimising this error are investigated. Theoretical friction factors are inferred from ring compression tests. Experimental results are reported for mild steel, copper and alum
The dynamic friction behaviour of polycarbonate (PC) was investigated at ambient ð26 CÞ and low temperature ðÀ60 CÞ using a split Hopkinson pressure bar (SHPB) and specimens of varying thicknesses. At ambient temperature, polytetrafluoroethylene (PTFE) and molybdenum disulphide ðMoS 2 Þ were found t
In the current investigation, the effect of specimen size in a Kolsky Bar experiment has been analyzed. By a series of experiments, it has been shown that while determining the dynamic stress-strain relationship of a material using a non-cylindrical specimen, a judicious choice of specimen dimension
