| Abstract | Ice crushing experiments similar to Gagnon and Daley (2005) have been repeated at twice the former high-speed video rate (1000 images/s) and with the intention of eliminating in-plane fractures that occurred in all previous tests. Rectangular thick sections (1 cm thickness) of lab-grown monocrystalline ice were confined between two thick Plexiglas plates and crushed at -10°C from one edge face at a rate of 1 cm/s using a transparent Plexiglas platen (1 cm thickness) inserted between the plates. Visual data were recorded from the side using the high-speed video and vertically through the platen using regular video. It was concluded that the system was too compliant to prevent the in-plane fractures, however, one test did show near full-thickness intact ice. From this test unambiguous pressure measurements were obtained for the intact and pulverized ice at the ice/platen interface utilizing the system's novel pressure sensor. As in the previous report, the production and flow of liquid in a thin layer at the intact ice/platen interface was evident. The apparatus was then modified significantly to reduce its compliance and more tests were conducted with the eventual desired result that in-plane fractures in the ice were eliminated. This confirmed that the apparatus is capable of yielding visual data of a 2-D slice of ice during crushing as though it was part of a larger piece of ice. |
