Abstract

Abstract

The dynamic response and failure behavior of AOW rock subjected to tensile loads has been studied experimentally. With the help of an one-stage light gas gun, the AOW rock samples, which were subjected to the plane plate impact by PMMA flyer with different speeds, have been recovered. The impact generated a tensile stress pulse of about 1.5 s duration in AOW rock by superposing rarefaction waves to induce spall. Based on the analyses of macro-and micro-examination for the recovered samples, the dynamic tensile strength of AOW rock was determined as 265.2-314.7 MPa.
