Abstract | Experiments were conducted to measure the mechanical properties of bulk ice rubble. Tests were performed under isothermal and plane strain conditions. The apparatus consists of two rectangular aluminum platens that are mounted on a test machine, two plexiglass side walls, and two rubber air-filled bags to apply confining stresses. Fresh water ice blocks were used to form bulk samples, approximately 0.5 m high, 0.5 m wide and 0.3 m thick. Tests were conducted using constant confining stresses and constant platen displacement rate. Results showed that at high strain rates, a peak stress can be reached. Local cracks or slips in the sample intermittently formed and " healed", thus causing sharp drops in the stresses. The peak stress was proportional to the confining stress and decreased with increasing strain rate. At low strain rates, stress drops (or slips) almost vanished and stresses increased monotonically with increasing strain. |
