Mini Round-Robin Test on the Split Hopkinson Pressure Bar

CODEN: JTEVAB

Abstract

It is known that the split Hopkinson pressure bar (SHPB) technique has not been standardized yet. A standardized SHPB technique is necessary to provide guidelines for determining the intrinsic material properties. One possibility to examine the consistency of the SHPB technique is to conduct a mini round-robin test. This paper examines whether consistent results can be achieved from three sets of SHPBs by conducting numerical simulations and physical tests on two metals: commercial copper and 6060-T5 aluminum. Both numerical simulation and physical tests employed three sets of SHPBs, namely, 12.7-mm-diameter SHPB made from the AISI 4140 steel, 13-mm-diameter SHPB made from the high-strength steel (HSS), and 14.5-mm-diameter SHPB made from maraging steel 350 (AISI 18Ni). The current study shows that consistent flow stresses (with an acceptable flow stress fluctuation of ±2.2 %) were obtained from these three sets of SHPBs, which indicates the possibility of SHPB standardization in the future.
