Accurately Replicate In Situ Conditions

Triaxial testing aims to accurately recreate high confining pressures, high temperatures, high pore fluid pressures, and a wide range of stress states.

For these applications, MTS offers triaxial testing assemblies that can be integrated within a rock testing system to create a complete triaxial testing solution. These assemblies include triaxial cells, a type of pressure vessel, along with a wide array of in-vessel accessories designed to withstand extreme conditions.

MTS TRIAXIAL ACCESSORIES BROCHURE

Simultaneously Apply Normal & Shearing Stresses

 MTS offers a direct shear package designed to extend the utility of MTS 816 Rock Mechanics Test Systems. With an integrated MTS Direct Shear Package, researchers can subject cylindrical, prismatic or irregularly shaped specimens of intact or jointed rock or concrete to both normal and shearing stresses, simultaneously.

MTS DIRECT SHEAR PACKAGE BROCHURE

Determine Porosity, Elastic Constants, Anisotropy & Fluid Saturation

The MTS Ultrasonic Velocity Test Solution is an effective, scalable research platform designed for studying the behavior of geomaterials core samples when subjected to temperatures and pressures that replicate extreme in situ environments. The highly detailed characterizations gained through such studies yield insight into the specimen’s porosity, elastic constants, anisotropy, fluid saturation and other critical attributes.

The MTS Ultrasonic Velocity Test Solution comprises state-of-the-art platen hardware, application software and electronics for control and data acquisition. These components are meticulously engineered and tightly integrated to deliver accurate, dependable performance in demanding triaxial test applications at temperatures up to 120°C (250°F) and pressures up to 140 MPa (20,000 psi).

This solution is specifically designed for use with the MTS Model 656 Triaxial Cell, an industry-leading accessory that can be seamlessly integrated into robust MTS Model 815 or Model 816 Rock Mechanics Test Systems. It can also be added as an upgrade to many already existing models of triaxial cells from MTS.
