Polyaxial Testing Systems
This unique experimental testing system is a customized solution used to study the behaviour of rock under various dimensional and compressive stress regimes (σ1 ≠ σ2 ≠ σ3). This fits to the research goals of geothermal energy researchers, hydrologists, petroleum reservoir engineers and researchers in the mining section, geophysics and geotechnical sectors. The systems are capable to test a wide range of materials from granite to mudstones and also for post-failure regime of high-strength brittle rocks.
Polyaxial rock testing systems are designed to induce stress on cubic samples via three independent controlled principal axes (σ1 ≠ σ2 ≠ σ3) up to 600 MPa. The sample chamber can house cubic samples up to 300 mm and has the option to be equipped with a temperature control up to 200 °C as well as a pore pressure device up to 210 MPa and the ability to have continuous acoustic emission recording, acoustic velocity and permeability (transient or steady state) measurements.
The complete system is fully automated and controlled by our flexible and programmable GEOsys Software. Various sensors, transducers, testing and experiment options are available.
