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
Neck localization during high rate extension of round bars is analyzed numerically. An axisymmetric problem formulation is given and the material is described as rate independent and elastic-plastic. The time history of neck development is investigated and effects of geometry and initial thickness i
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
