Abstract
The paper summarizes the results of ice destruction at shock loads (up to 1500 m/s). A brief literary review was sufficient for formulating research tasks, including impact experiment and a computational experiment. The results of impact experiment (≤159 m/s) were presented. The freezing temperature of ice samples varied from − 10°C to − 21°C. Similar pattern of ice destruction was noted in the quantitative test, which conducted especially for validation of the numerical method. The results of an underwater explosion of 4 kg of EE under 130-days-old “needle” ice cover are represented. Some capability of non-commercial software package is demonstrated. The impact resistance of single and double plates was qualitatively and quantitatively evaluated. It was established that the plates could protect against impact by an ice ball only up to 500 m/s.
