Feasibility of a 6-Inch Split Hopkinson Pressure Bar (SHPB)

Abstract

The main objective of this study was to assess the feasibility of a 6-inch Split Hopkinson Pressure Bar, SHPB, to test cementitious materials at high rates of loading. There is a need to do non-destructive tests on concrete structures, but the current SHPB's are only 2 to 3 inches in diameter and therefore they are not able to test material samples 6-inches in diameter which is typical size of concrete specimens cored in the field. This effort included a thorough mathematical analysis in parallel with numerical calculations. The study focused on the SHPB system, the assumption made, their validity in a larger apparatus, and the problems and issues associated with a size change.
