Limiting the influence of friction on the split Hopkinson pressure bar tests by using a ring specimen

The deformation of a ring under axial compression is analyzed in order to estimate a favorable ring specimen geometry capable of limiting the influence of friction on the stress–strain curve obtained from SHPB tests. The analysis shows that the use of a ring specimen with a large inner diameter and...
