PROBLEM TO BE SOLVED: To provide an ice fracture model configured to properly reproduce brittle fracture and crack fracture generated in ice due to compressive load, and a method of simulating fracture analysis of ice.SOLUTION: An ice fracture analysis simulation method includes the steps of: setting an ice fracture model 100 having a brittle fracture section model 110 formed of a particle model, and a crack fracture section model 120 formed of a finite element model; modeling brittle fracture and bulging deformation to be caused by the brittle fracture, on the basis of a particle method for the brittle fracture section model 110 which receives compressive load, and performing ice fracture simulation for modeling crack fracture, on the crack fracture section model 120 on receipt of bulging deformation of the brittle fracture section model 110, on the basis of a finite element method; and outputting a result of the ice fracture simulation. |
