Abstract: A meshless Lagrangian method based on the moving particle semi-implicit (MPS) method is employed on the basis of continuum mechanics and applied to simulate ice fracture problems in this study. Ice can be considered as homogeneous isotropic elastic material before the fracture happened. When failure occurs, the connection between particles will be cut off. This process only occurs when fractures develop between two particles. The location and direction of fractures are calculated according to the maximum tensile stress theory. The developed method is adopted to solve the ice failure for three-point bending test and the wedge level ice test problems, and the simulated results are validated by comparing with the experimental results conducted in an ice tank.
