The behavior limestone under explosive load

Limestone behavior under explosive loading was investigated. The behavior of the limestone by the action of the three types of explosives, including granular, ammonite and emulsion explosives was studied in detail. The shape and diameter of the explosion craters were obtained. The observed fragments after the blast have been classified as large, medium and small fragments. Three full-scale experiments were carried out. The research results can be used as a qualitative test for the approbation of numerical methods

Research of the behavior of ice on water under explosive loads

Complex theoretical and experimental studies of the behavior of ice under dynamic loads are presented. New experimental data about blast of snow-covered ice have been obtained. A complete coincidence of the experimental data of 2013 and 2017 was found. Test calculations, including impact test have been carried out. Shock adiabatics of ice and water are presented. The behavior of the ice block on the water under explosion was investigated. The velocity of the free surface, the volume of ice destruction, the diameter of the explosive lane in ice cover were calculated. Recommendations for more effective ice destruction under these conditions were given
