EXTENDED SPLIT-HOPKINSON BAR ANALYSIS FOR ATTENUATING MATERIALS

The split-Hopkinson pressure bar (SHPB) is briefly reviewed, as well as the standard analysis procedure for reducing the data. The limits of the applicability of the standard procedure is discussed, and the modified Lagrangian analysis procedure is described. Experimental results for two soil types are presented to demonstrate the usefulnes of this approach. The Lagrangian analysis technique can be used effectively to resolve the early time rsponse of soil specimens in a SHPB experiment. Coupling the Lagrangian procedure with the standard procedure allows for a complete description of the soil stress-strain response.
