Modified KCC model for modelling mechanical behaviour of quartz sandstone under triaxial compression from low to high confining pressures

It is a challenge to simulate numerically the mechanical behaviours of rocks under triaxial compression at low and high confining pressures due to the limitations of constitutive models of rock-like brittle materials. This paper is devoted to developing a modified KCC (Karagozian and Case concrete) model for numerical modelling of the mechanical behaviours of Fontainebleau quartz sandstone under triaxial compression tests from low to high...
