Instruments and Methods: A Shear-creep System for Studying Grain-boundary Behaviour in Ice
Abstract:We present here a shear-creep apparatus. This has been designed to study grain-boundary behaviour in ice bi-crystals. The design and dimensions of this apparatus were determined by taking into account the results of earlier tests, performed on the same types of sample. Improvement with the new device is obtained; it allows a displacement with two degrees of freedom in the grain-boundary plane, and direct observations of micro-structural changes during the test.
