Abstract
A model of freshwater ice behavior under impact compression is suggested. To get the parameters (mechanical properties of ice at high-speed loading) of the model the Kolsky method was used. The necessary data of parameters were obtained at a strain rate of 1.4•10^3 s^-1. A new procedural approach and an experimental data filtering algorithm were proposed. In addition, a phenomenological model of ice was offered, which made it possible to obtain a relationship between the measured force and the parameters of the material. The verification of the model was done ac-cording to the results of experiments in which forces were obtained in the study of the destruction of ice samples for high strain rates. It was shown that the analytical force model describes the experimental data well.
