Abstract

Abstract

The dynamic mechanical properties of soft materials have attracted great attention, and the separated Hopkinson pressure bar (SHPB) technique is the most important test method at present. However, the SHPB technique still needs some improvements when it is applied to extra-soft materials. So, a double-striker electromagnetic driving SHPB system was developed. In the developed system, the bars were made of polycarbonate, and the double-striker scheme was designed to precisely control the velocities of the strikers. Both the aluminum SHPB facility and the double-striker electromagnetic driving SHPB system were employed to carry out dynamic experiments on the silicone, and the agreement between the test results by these two systems indicated the reliability of the innovative system. And dynamic mechanical properties of PVA hydrogels were successfully tested by the double-striker electromagnetic driving SHPB system.
