Abstract

Subcritical crack growth is important for the long-term behavior of rock and can be used to evaluate the long- term stability of underground and surface structures in rock masses. In this study the mode II subcritical crack growth parameters were determined experimentally using the double notch shear test. A series of tests were performed to determine the appropriate geometry for the double notch shear test. The mode II stress intensity factor was determined using finite element analysis using the displacement extrapolation method. The subcritical crack growth parameters in Flagstaff sandstone were determined to be n =28.27 and A =0.00647 m/s.
