Abstract: Ice crushing has been a challenging process to model because of the large number of particles and fragments, which present computational difficulty, as well as the non-trivial constitutive behavior of the material. The Material Point Method (MPM) is a promising modeling technique in situations with high deformations where the material transitions from solid to granular. A continuum damage MPM has been developed to model dynamic ice crushing under indentation. We reproduce the significant experimentally observed phenomena, such as the localized damage near the indenter, ejection of fine particles, spalls, and cracks in the solid part of the sample. Moreover, the modelling approach reproduces important features of ice-structure interaction, most notably the formation and evolution of high-pressure zones. Our approach can potentially contribute to assessing risks in ice-structure interaction, iceberg keel impacts on subsea pipelines, ice-pipe-soil interactions, and other applications.
