Abstract
Rocks exhibit elastic behavior at room temperature and visco-elastic behavior at elevated temperatures. It is important to understand the latter for application in the thermal fragmentation of rocks. Test results are presented on the short-time thermoviscoelastic behavior of charcoal granite and Dresser basalt at elevated temperatures. Optical means have been used to measure creep compliance of Dresser basalt and charcoal granite rock specimens. Within the temperature range of 850 deg. to 1,000 deg. C the temperature-time-shift theory has been found to be applicable.
