Examination of the Mechanical Properties for a Kayenta Sandstone from the Mixed Company Site.

Abstract

An experimental and theoretical examination is conducted for the static and dynamic mechanical behavior of a highly porous, dry sandstone from the MIXED COMPANY event site. The static behavior is obtained from data of hydrostatic loading, uniaxial strain loading, and uniaxial stress loading to failure for various confining pressures. The dynamic behavior is obtained from data of plane wave, plate-impact tests and spherical stress wave tests using 5.08-cm-diameter explosive spheres. In-material measurements are made of the particle velocity and stress-time histories which characterize the dynamic response. The experimental results exhibit several complex featrues such as: irreversible compaction dependent upon both mean normal stress and shear stress; dilatancy; strain hardening and strain rate dependent response.
