Comments on the Effect of Radial Inertia in the Kolsky Bar Test for an Incompressible Material

  • T. L. WarrenEmail author

Brief Technical Note


We present equations that show the effect of radial inertia for incompressible samples that are in dynamic force equilibrium during the split Hopkinson pressure bar test or Kolsky bar test. For steel samples the radial inertia effect can be neglected; however, radial inertia can be important for very soft materials.
