Split-Hopkinson Pressure Bar (SHPB) method is the most versatile technique to evaluate the stress-strain relations of materials at high rate of strain. Over the decades, the method has been improved and developed, and now, it has been widely applied to investigate the various kinds of mechanical properties of materials under impact loading. Recent research activities and techniques related to this famous method are reviewed in the present paper.

The Split Hopkinson pressure bar (SHPB) method has been used for impact tests such as compression and shearing, and is currently modified for tensile test, since the various kinds of high strength sheet metals are greatly concerned with the safety and the energy saving demands for high velocity vehicles. Evaluation of mechanical properties by a tensile test using the SHPB, however, has not been clarified, since the testing conditions such as specimen geometry and settings are quite different from the usually operated compression version. In the present paper, we try to identify the characteristics of the method, particularly such as a yielding phenomena, and have clarified the effect of three dimensional stress wave propagation in the tensile test where a large ratio of sectional areas between a specimen and a loading bar is usually inevitable.
