Hydrothermal rotary shear apparatus
Custom-built (in-house) rotary shear apparatus consisting of an internally heated water-filled pressure vessel housed inside a commercial 100 kN Instron load frame. The ring-shaped pistons have an outside diameter of 28 mm and an inside diameter of 22 mm, which translates to a maximum normal stress of ~250 MPa and velocities in the range 1 nm/s - 1 cm/s (defined on the average radius), depending on gear box and motor configuration. Fluid pressure is up to 300 MPa and temperature up to 700 ºC. Acoustic sensors are mounted at the bottom vessel, with the possibility of an additional sensor at the top.

Rotary shear apparatus
Room temperature rotary shear apparatus with rotational speeds of 0.001 to 12.5 rpm. Default ring size is 70/100 outside/inside diameter which translates to velocities from 5 micron/s up to 5 cm/s. Alternative ring sets with 80/100 and 30/60 are available. Also included are four pore fluid pressure holes on the rotational side of the sample for measuring local pore fluid pressure or temperature.
