The Stripa project was designed to test the agreement between theoretical and actual rock fracture times of a rock block loaded with a physical as well as a thermal load. Laboratory testing consisted of physically loading center-drilled cubes of rock, 0. 3 m on a side, uniaxially from 0 to 25 MPa. These were then thermally loaded with a nominal 3. 7 kW (factory rating) cylindrical heater until failure occurred. This time to failure was recorded for comparison with a direct mathematical and a finite element solution. For both cases, calculations were performed at specific time-steps and an estimated failure time calculated from the compiled results.
