Аннотация

In this paper, results of experimental and numerical research of ice destruction under shock and explosive loads were summarized. Full-scale experiments and laboratory impact experiments were performed. Specially for carrying out full-scale tests the mobile laboratory "Explosive destruction of natural materials" was organized. Last year's results of full scale underwater explosive tests are given. The diameter of the polynya (lane) and the state of the ice edge were studied. The results of the experiment in which the target was three-layer ice barriers are presented. The ice was broken into fragments, and the projectile was slightly deformed. Briefly, the mathematical model of ice behavior is described. The numerical method is based on the Lagrangian approach and contained a new way for isolating discontinuity surfaces of material. The capabilities of the non-commercial software package were demonstrated. The results of the quantitative test are given. The deep penetration of a container with inert filler into ice on water was modeled. New research tasks have been formulated.
