Acoustic Emissions Testing

Acoustic emissions testing provides a nondestructive means of accurately characterizing the properties of rock core specimens under triaxial test conditions. After in situ conditions are reproduced, changes in loads, confining pressures, pore pressures and temperatures are applied. These changes have the potential to produce ultrasonic events. By monitoring and recording acoustic emissions, test professionals gain new insight into specimen events such as microcracking, pore collapse and grain boundary sliding. Ultimately, the data helps create more accurate models of rock reservoirs and formations.

MTS has offered rock mechanics testing systems for more than 40 years, and our expertise in developing custom solutions for this application remains unmatched. Today, MTS provides complete, fully integrated solutions for rock mechanics testing, including the high-performance piezoelectric transducers that facilitate highly precise measurements of critical geological material characteristics via acoustic emissions monitoring.
