MTS Systems

Model 815 and 816 Rock Mechanics Test Systems

The MTS Model 815 and 816 rock mechanics test systems deliver exactly what geological materials experts need to work with confidence: fully integrated solutions that can be configured to test all types of rock in both basic and highly complex applications. Designed to test everything from soft sandstone to high-strength brittle rock, these systems combine versatile servohydraulic load frames with precise digital controls, flexible software and specialized accessories for uniaxial and triaxial testing.

Key Features & Benefits

  • Precise — Highly stiff load frame, fixed crosshead and single-ended actuators for carefully controlled studies
  • Versatile — Space plates support a range of specimen sizes
  • Accurate / Repeatable Results — Can characterize high-temperature, high-pressure extremes
  • Easy, Intuitive Use — Pre-engineered for triaxial cell installation

*Although the Load Frame assembly is capable of producing the indicated force in tension, the actual tensile
force limit is dependent on the attachment hardware (e.g., threaded connectors) that attach the gripping
fixtures to the crosshead and actuator).
