Triaxial Testing

Triaxial testing provides realistic simulations of in situ rock properties. By subjecting small specimens to axial and lateral stress plus high temperatures, triaxial testing helps predict how the entire rock mass will respond to changes in load, stress, displacements, pore pressure, pore volume, failure and other conditions. Typical specimens are rock core samples with length-to-width ratios of 2:1 or greater, and sizes ranging from one to four inches. Axial stress is applied through the load frame actuator and confining stress is applied with a triaxial cell.

MTS manufactured its first rock mechanics test system more than 40 years ago. We provide unmatched experience and expertise in both standard and custom triaxial testing solutions. Our fully integrated offerings include load frame hardware, triaxial cells, specialized in-vessel accessories and a powerful software platform for data analysis. Specifically, MTS delivers:
