Abstract

The scale effect on subcritical crack growth in rock is important to extrapolate the laboratory test results to the field scale design. A constant stress-rate test has been performed to estimate the mode I and II subcritical crack growth parameters for Coconino sandstone. The experimental results show that the subcritical crack growth parameters of mode I and mode II loading are similar to each other. The subcritical crack growth parameter A values increase with increasing specimen size, whereas the subcritical crack growth parameter n values are independent of specimen size. The subcritical crack growth parameter n was determined to be 35 to 36, and A was determined to be 1.17×10 -2 to 3.02×10-2 m/s.
