Brittle Failure Simulation of Ice Beam Using a Fully Lagrangian Particle Method

Abstract

A realistic numerical simulation technology using a particle-based fluid-structure interaction (FSI) model is combined with a brittle fracture algorithm to predict the fluid-ice-structure interaction. With respect to the failure of ice, itis modeled as a brittle fracture of elastic body by applying a novel FSI model based on the Moving Particle Semi-implicit (MPS) method. For verifying the developed fracture algorithm, a series of numerical simulation for 3-point bending tests with ice beam are performed and compared with the experiments carried out in the ice room. And then, for the application of the developed FSI model, a dropping water droplet interacting with a cantilever ice beam is simulated with and without the fracture algorithm. As the results from the simulation, it is seen that the consequent effects of fracture that might be occurred in the process of FSI simulation is available to be studied.
