Critical Stress Intensity Factor (KIc) Measurements at High Loading Rates for Polycrystalline Ice

Part of the International Union of Theoretical and Applied Mechanics book series (IUTAM)


In this paper results are presented from experiments to measure KIc the critical stress intensity factor, at -4, -11, and -24°C. Rectangular bars with a slot ending in a sharp crack in one side were broken in four point bending. The mean values were 118 ± 32 kN m-3/2 (44 samples) at -4°C, 119 ± 34 KN m-3/2 (40 samples) at -11°C, and 108 ± 21 KN m-3/2 (44 samples) at -24°C. These agree well with the results of other studies, and show that G, the strain energy release rate is close to twice the surface energy, Γ (overall mean for KICis 115 KN m-3/2, implies G equals 1.38 Jm-2 compared to 0.2 Jm-2 for 2Γ.

Some preliminary results from the measurement of crack opening displacement are also presented.
