Paper presented at the 57th U.S. Rock Mechanics/Geomechanics Symposium, June 25–28, 2023
Paper Number: ARMA-2023-0288
... ABSTRACT Granitic rock subjected to multiple load/unload/reload cycles is observed to have a much lower stiffness on the first loading step compared to subsequent cycles. This apparent work hardening has been proposed to provide unique insight into a rock's stress history, making...

... of geothermal energy we’re talking about is found deep underground in certain rocks, like granite and gneiss. There are many ways to get this energy out of the ground, but the most common one is called an enhanced geothermal system. This involves creating fractures in the rock using a special fluid, so that hot...
