AN INVESTIGATION OF THE ELASTIC STRESS-STRAIN BEHAVIOR OF A BANDED SANDSTONE AND A SANDSTONE-LIKE MATERIAL

This paper presents a complete methodology that enables the independent determination of the 5 mechanical parameters required to describe the elastic behavior of transverse isotropic rock. This methodology is unique in that it requires only a single specimen. The specimen is subjected to a series of specific stress conditions and from each stress condition a different parameter can be determined. An advantage of the methodology is that the difficulty of material variability between specimens is largely eliminated. Results compare favorably to other more conventional frameworks such as uniaxial testing and Brazilian compression. The majority of the testing was performed on a natural anisotropic sandstone. The methodology was implemented to consider possible differences in the response of both materials to compressive and tensile stress regimes. Over the range of stresses considered, the differences between the compressive and tensile stiffnesses are surprisingly small.
