| n experimental technique has been developed that is capable of (1) controlling the triaxial stress state in the specimen, (2) dynamically loading the specimen in multiaxial compression, and (3) allowing the recovery of the sample after loaded by a single and well-defined pulse for the characterization of the failure mode. Hydrostatic pressure is introduced to the test section of a compression Kolsky bar to create dynamic triaxial loading conditions on sand specimens. Both the test section and the free end of the transmission bar in a Kolsky bar setup are fitted with two hydraulic pressure chambers. After a desired hydrostatic pressure is applied to the specimen, an impact-generated axial load is applied through the incident bar for characterizing the dynamic shear response. Quasi-static and dynamic triaxial compression experiments have been performed on Quikrete... |
