A coupled discrete-element model of fluid-saturated rock and the results of studying of the impact of a fluid on the shear strength of a rock under combined compression and shear
Dimaki, Andrey V.; Shilko, Evgeny V.; Psakhie, Sergey G. (CIMNE, 2017)
Conference report
Open AccessWithin a discrete-element model of a porous permeable elastic-plastic rock, filled with a fluid, we have studied the shear strength of a fractured interface zone (a shear band) between blocks of a geological medium subject ... -
A theoretical investigation of a mechanical response of fluid-saturated porous materials based on a coupled discrete-continuum approach
