Model experiment is an essential approach for investigating ice-structure interaction. The model ice employed in different ice tank laboratories and ice indentation tests (including saline ice, urea ice, and EG/AD/S ice, etc.) exhibits variations, and studying the mechanical characteristics of various model ices is crucial for conducting model experiments. In this study, the aforementioned three types of model ice were prepared in a low-temperature laboratory, uniaxial compression tests were performed, and the macroscopic failure characteristics of the model ice under different strain rates were comparatively analyzed; based on the Digital Image Correlation (DIC), the full-field strain and crack propagation process of the model ice were analyzed in detail, and the differences in the mechanical properties of the model ice were ultimately examined. The results indicate that saline ice exhibits the most similar failure behavior to sea ice, urea ice presents layered failure at high strain rates, and EG/AD/S model ice demonstrates predominantly ductile failure characteristics; the three types of model ice exhibit distinct crack propagation characteristics, with saline ice and urea ice possessing ductile and brittle failure intervals comparable to those of sea ice.
