The split Hopkinson bar (SHB) method was proposed by Kolsky in 1949 as a high strain rate compression test. Since then, the SHB method has been improved by numerous researchers in the worldwide, and has been expanded to various loading mode, such as, tension, torsion and bending. The present paper outlines the principle of the SHB method for high deformation rate testing. Recently, polymer materials have been widely used as a structural material for automobile. Thus, the present paper focuses on the evaluation technique of the compressive properties of polymer materials, with showing the flow of the data processing on the SHB method.
