Abstract: In the study of ice-structure interactions through numerical simulation, accurately simulating the complex mechanical properties of ice remains a core technical challenge. To precisely replicate the complex mechanical properties of natural ice materials in numerical simulations, this paper, based on peridynamics theory, introduces a numerical simulation method for the brittle anisotropy of single-crystal ice. Different fracture criteria were incorporated, and an unconfined brittle uniaxial compression numerical simulation experiment on single-crystal ice was conducted, leading to the development of a peridynamics method for simulating the brittle anisotropy of single-crystal ice. The model was used to analyze the crack propagation pattern, revealing pronounced oblique through-cracks, similar to those observed in existing model experiments. The findings of this study provide a fundamental reference for establishing numerical simulation methods for the anisotropy of polycrystalline ice.
