Studies on model-scale ice using micro-potential-based peridynamics
2021
Abstract This paper represents a numerical scale model of ice used to simulate the model experiment of ice-ship and ice-structure interaction scenarios. The micro-potential-based peridynamic formulations proposed in [7] are used to simulate the deformation and fracture of model-scale ice. In this configuration, a square measure of the bond length change is employed and validated with the finite element method and theoretical solution. In present work, different scale factors λ = 10,20,40 and 50 are investigated and discussed concerning the m-convergence, δ-convergence, and the flexible strength of a cantilever beam. It is essential in the field of ice tank numerical simulation of the ice-structure interactions. The dimensionless of the horizon size to the length of the model ( δ / L ) is also analyzed. The linearity between macroscopic mechanical properties and the relative horizon size δ / L is found.
