Effect of hydraulic hysteresis and degree of saturation of infill materials on the behavior of an infilled rock fracture

• We present results from a new testing approach adapted to characterize the shear behavior of unsat. infilled rock fractures.
• We analyze the hydraulic and mechanical behaviors of infilled fractures during drying and wetting.
• We use an alternate approach to characterize the impact of degree of saturation on the shear behavior of infilled fracture.
