A method to express the distribution of the experimental results of fracture toughness of ice was investigated by postulating the Weibull distribution with three parameters. The data were taken from the previous experiments conducted to study the effect of loading rate on the fracture toughness9), 10). Weibull parameters were estimated by several estimation methods11), 12) and the parameters obtained were compared with each other. The effect of loading rate together with that of specimen size on the parameters were discusssd at three loading rate ranges. It was confirmed that the parameters estimated were closely related to the experimental value of fracture toughness.
