520 3# ‡aIce-failure mechanism close to contact has been studied in series of small-scale crushing tests at high indentation velocities. Iterative numerical model based on successive shear failure was used to predict crushing behaviour. Concludes that contact consists of narrow line where melting point is attained at high indentation rates. Indications are that ratio of shear strength to contact pressure controls fractal behaviour of ice crushing. Contact pressure and shear strength are related to indentation velocity. As indentation rate increases, ratio of shear strength to contact pressure decreases, causing finer fragmentation of crushed ice.
