Triaxial Rock Physics Ensemble including: 1500KN Servo controlled load frame/400 MPa Pressure vessel with 400ºC Furnace/Confining pressure intensifier.

Our servo-controlled triaxial rock deformation and rock physics ensemble can operate at confining pressures to 400 MPa and temperatures to 400ºC. It incorporates an independent 400 MPa pore fluid pressure intensifier/porosimeter/permeameter, and load is applied through a 1500 kN servo-controlled actuator. Rock samples (40mm in diameter by 100mm long) are enclosed in engineered polymer jackets with 12 transducer mounting points. This allows real-time monitoring of changes in elastic wave velocities (both P and S), electrical conductivity and electrical potential, and 3D location of acoustic emission events generated during crack propagation.
