Aparatus Features:
- Maximum 103.5MPa (15,000PSI / 1035BAR) Confining Pressure
- Internal electrical heater system capable of 200°C operating temperature with ramp function from GIC-A software PID control
- Maximum 70MPa (10,000PSI / 700BAR) Pore pressure. Pore pressure is applied through two flow ports to flow distribution grooves on the axial platen face plates
- Axial load applying platens incorporating P-S1-S2 acoustic transducers
- 4 radially equispaced lateral P-S1-S2 acoustic transducers within the cell annulus positioned at the sample mid height
- 12 lateral Acoustic Emission (AE) sensors
orientated radially at strategic positions around the core sleeve - 6 axial AE sensors housed in the axial platens (3 in each faceplate)
- 2 channel strain gauged cantilever in the cell annulus for radial deformation measurements
- 2 LVDTs externally mounted on the axial platens for axial strain and deflection calculation
- Maximum axial load of 450kN with standard axial platens relating to 220MPa contact stress on a Ø50.8mm (Ø2”) sample.
- Approx 2000kN load can be applied with optional high strength axial acoustic platens resulting in contact stress of approx 1000MPa on a Ø50.8mm (Ø2”) sample
- Designed to accommodate sample size Ø50.8mm (2”) by 127mm (5”) long
