... ABSTRACT: The finite element code ABAQUS is used to model a typical granite specimen subjected to either uniaxial or biaxial compression, with two pre-fabricated flaws with the geometry 2a-30-30 in which only one flaw is pressurized. The maximum and minimum principal stresses as well...

... ABSTRACT: This paper investigates the effect that small sample sizes have on uncertainties associated with intact rock strength parameter estimations, using various combinations of strength data (namely, uniaxial and triaxial compressive, uniaxial compressive and indirect tensile...

... diffraction tests were performed to determine the mineralogical composition of shale. The tests showed that the specimens were rich in carbonate content with minor percentage of clay minerals. A suite of uniaxial and triaxial compressive tests was performed on both parallel and perpendicular that determined...

... the permeability evolution with progressive damage in intact rock when it is subjected to incremental mechanical loading. The rock response during uniaxial and triaxial loadings is simulated with and without taking into account the hydro-mechanical interactions between fluid and solid part of the rock...

... ABSTRACT: The rheological behavior of salt rock is studied by both uniaxial and triaxial relaxation tests. In order to investigate the relaxation behavior of salt rock, stepwise relaxation tests were performed after the sample had been subjected to different pre-relaxation creep strains...
