Infrastructure belongs to:
For rock deformation experiments we handle different apparatuses, allowing to perform brittle (low temperature) tests on large rock samples (MTS servo-hydraulic press) and high temperature (ductile) experiments on small samples (Paterson-type gas deformation apparatus at high confining pressure, uniaxial creep rig at atmospheric pressure). The following facilities are operated: servohydraulic MTS press, gas deformation apparatus and high temperature creep apparatus.
