This project is intended to upgrade the ultrasonic                         measurement system in the Rock Mechanics Laboratory at The                      Pennsylvania State University. A new pulse generator, and a new                 digital oscilloscope will be the main components of the                         upgraded system.                                                                     The strain relaxation of rocks that have been subjected to                 stress has two major components; one is instantaneous and the                   other is time-dependent. In large part the time-dependent strain                relaxation of a rock involves the formation and opening of                      microcracks, and this relaxation can be monitored by measuring the              changes in the ultrasonic properties of the rock. The upgraded                  ultrasonic measuring system will allow the Rock Mechanics                       Laboratory to fully exploit the potential of the time-dependent                 strain relaxation technique for interpreting the stress history of              rocks under deep earth conditions.
