Experimental study and discrete element method modeling of compression and permeability behaviors of weakly anisotropic sandstones

Full understanding of the compression and permeability behaviors of weakly anisotropic sandstones is a major challenge. The present work aims to address this challenging task through a series of triaxial compression tests equipped with permeability measurement on sandstone specimens to examine their...
