Ice Physics - main

The Ice Physics Laboratory  consists of a 5 chamber complex of inter-connected cold rooms controllable from 0 to -30 deg C:

(1) Ice Preparation Laboratory,
(2) Mechanical Test Laboratory,
(3) Ice Analysis Laboratory,
(4) Ice Machine Shop,
(5) Ice Store

Research Equipment Includes:

Ice Friction Apparatus

Triaxial deformation cell for ice operating at low temperature (down to -90ºC) and high pressures (300 MPa) utilizing a servo-controlled 100 kN actuator, with AE monitoring and P-wave velocity measurements, using 40mm diameter by 100mm long specimens.

Triaxial Deformation & Tomography Cell, consisting of 4 servo-hydraulic 6 tonne actuators loading an ice specimen in the y and z directions and fluid confining pressure providing the x-component stress (essentially a biaxial loading rig combined

with a pressure vessel.

The rig operates at confining pressures of up to 50 MPa, temperatures down to -40°C, and strain rates in the 10-4/s to 10-8/s, and takes an ice specimen up to 80mm x 160mm x 40mm.

The Cold Room Facilities are available for use by arrangement. For further information or to arrange use of the coldroom facilities please contact Laboratory Manager.
