Abstract : This report includes a compilation of both physical and mechanical property data for use in developing in situ constitutive relations. The in situ stress state is defined for a variety of rock types and structural environments. Triaxial tests, including hydrostatic and uniaxial strain tests, were conducted on sandstone and shale from the GASBUGGY site. Problems studied include the intact versus residual failure envelopes, dilatant behavior and the dependency of modulus on strain-rate. Salt cores from both the GNOME event and SALMON event were tested under triaxial conditions; both compression and extension failure enveloped were determined. Originator keywords include: material property, and reduced displacement potential (RDP).
