“…Although there have been a number of published studies on hypervelocity impact and shock studies of ice [5][6][7][8][9][10][11] performed so as to understand what happens in the Solar System on a regular basis without human involvement, ballistic impact on ice targets at more modest impact velocities (100 m/s) has been comparatively little studied [12][13][14][15][16][17][18]. In order to design a space probe capable of surviving impact on Europa, it is necessary to know the mechanical properties of water-ice at the appropriate strain rate and temperature.…”

Space penetrators are a potential method of inserting instrumentation onto ice-covered bodies in the solar system. Part of a study to see whether this is feasible involves numerically simulating impact of the penetrator into ice at impact velocities of a few 100 m/s. In order to do this accurately, it is necessary to have a constitutive model for water ice that is valid at the strain rates and temperatures relevant to impact in the Outer Solar System. This paper reports certain issues and difficulties that arose during a study to obtain this data.

The behaviour of freshwater ice under the action of detonation products has been studied. As objects of the study was chosen snow covered ice of medium thickness. The ice cover of 2018 and 2017 on the Tom River was considered in current research. The age of the ice was approximate 130 days, but the temperature of its formation was different. In the first case (2017), the ice formation temperature was 7.5 % lower than in the second case. The sizes of the lanes in the snow covered ice after detonation of 4 kg of emulsion explosive are obtained. It was established that in the second case the diameter of the lane was 15% smaller than in the first case. The ice edge of the lane in the snow-covered and bare ice was determined. The edge of the needle ice, which had a stepped shape, is presented. A qualitative and quantitative assessment of the destruction of ice under explosive loads is given. It was found that the temperature of ice formation influenced the process of its destruction under explosive loads.

“…The experimental method, if property conducted, can produce the most reliable results of ice damage and relationships between experimental variables (for instance, parameters of charges, the distance between charges and ice cove, and characteristics of ice cover) and blast effects. There have been a number of field experiments on the dynamic response of the ice under the action of the explosion wave [6][7][8][9][10][11][12][13][14][15]. However, since the destruction of ice cover under explosion takes place in a short moment, limited data can be collected during this process [16][17][18].…”

Along with the development in arctic region, the icebreaking technologies are gradually becoming the focus. As one of the most powerful and effective way to breaking ice, especially in the ability to solve ice jams, the study of the behaviour of the sea and river ice under dynamic loads is an urgent subject of scientific research and it attracts extensive attention. In addition, the temperature change in the process of ice failure cannot be neglected since that temperature plays an important role in the mechanical properties of the ice. In this study, a fully coupled thermoelastic ordinary state-based Peridynamic model is employed to investigate fragmentation of ice cover subjected to an underwater explosion. Both the deformation effect on the thermal effects and the thermal effects on deformation are taken into consideration. The pressure shocks generated by the underwater explosion are applied to the bottom surface of the ice cover for non-uniform load distributions. Crack propagation paths are investigated, the damage is predicted and compared with existing experimental results. The corresponding temperature distributions are also examined. Furthermore, the ice failure mode in both the top surface and the bottom surface of the ice sheet is investigated.
