Stress-strain behavior of a granodiorite and two graywackes on compression to 20 kilobars

Abstract: The complete stress‐strain equation of state for a granodiorite and two graywacke sandstones has been determined on loading to 20 kb axial stress at room temperature. Data under conditions of hydrostatic, uniaxial stress at various confining pressures and uniaxial strain loading are synthesized to define the behavior of these rocks. For the granodiorite it is observed that the onset of dilatancy as well as intersection of the failure envelope is independent of loading path. No dilatant behavior is observed on … Show more

“…Statically, the behavior of granite in triaxial compression was simulated at different levels of confining pressure. The numerical simulations closely resembled a series of experiments performed by Schock et al [4] to examine the yield, bulking and failure characteristics of Climax Stock granodiorite, the same rock formation where PILE DRIVER was detonated. These static simulations were used to determine the material parameters for the yield and bulking models.…”

“…The model assumes the material is isotropic and applies the mathematical structure of plasticity theory to capture the basic features of the mechanical response of geological materials, including the effects of bulking, yielding, material damage, and porous compaction on the material response. This model has been shown to be in good agreement with the static data of Schock et al (1973), as well as explosion data in granite [Antoun et al (2001)]. One of the shortcomings of this model is that it does not account for directional effects associated with wave propagation.…”
