Experimental Study for Dynamic Mechanical Properties of Shale using Split Hopkinson Pressure Bar

The dynamic mechanical properties of shale are basic for shale gas reservoir reforming. In order to reveal the law of shale's mechanical properties changing with the strain rate, the SHPB impact test has been done. Through the analysis of the experimental results, the relationship between shale's mechanical parameters with strain rate is obtained. The experimental results can describe shale's dynamic properties under the impact load. The results will provide the theoretical basis and calculation parameters for shale gas reservoir reforming and numerical simulation.
