Abstract : A fairly simple modification of the split Hopkinson bar SHB method is presented that extends significantly the scope of the Kolsky method in studying the effects of strain rate and strain-rate history on the physical and mechanical properties. The developed modification of the SHB method makes it possible to conduct incremental tests with alternating dynamic loading. Examples illustrating the possibilities of the modifications described are included.
