Technical tracks and sessions

The annual rock mechanics / geomechanics symposium encompasses all aspects of rock mechanics, rock engineering, and geomechanics, with a focus on fundamental, practical, and educational issues facing our profession. Scientific and engineering papers at the Texas 2021 symposium will cover topics in the six technical tracks described below: civil, mining, petroleum – conventional and unconventional, geothermal, and interdisciplinary.
