Since the material properties of sea ice are complex and related to superficial knowledge, developing effective material constitutive models and improving numerical methods are of crucial importance in ice-ship interaction analysis. This paper summarizes the main investigating methods for ship-ice interaction analysis, which are testing method, FEM (finite element method), DEM (discrete element method) and probabilistic method. Direct data can be obtained through on-site measurement tests, and it is also the basis for sea ice material constitutive models, but tests are always high-cost. FEM has a profound theoretical foundation and is easy to implement, but is limited in simulation of brittle crush behavior and fragments' large-scale movement. Nevertheless, DEM has better abilities in simulating these characteristics, but DEM still needs further development. Owing to the randomness of some features of ice, such as size and orientation of inner flaws, probabilistic method is also considered to be suitable for the research on ship-ice interaction.
