Experimental and numerical (EFG method) studies on sedimentary rock under varied salinity conditions

In this paper, uniaxial compressive strength (UCS) tests were performed on cylindrical Gosford sandstone specimens of varying salinity to quantify the degradation in the modulus of elasticity properties. Three-point bending (TPB) tests of a single-edge notched beam (SENB) were performed to estimate the fracture toughness. To accurately model the phenomenon of degradation in the presence of non-homogeneity and varying salinity, a modified...
