.... At higher confinement the stress envelope makes a transition to the CD defined envelope (Diederichs & Martin 2010). Few test data in this range are available. Another objective is to detect the effect of low confinement on CI. 2 ROCKS INVESTIGATED Five different sedimentary rocks were selected...

... and under an anisotropic in situ stress field, the process of spalling can form notch-like geometries. Extensive research over the last few decades, as summarized by Martin (1997), Kaiser et al. (2000) and by Diederichs (2003,2007), has demonstrated that brittle non-porous rocks exhibit an maximum long term...
