This paper demonstrates the application of a 3-D random lattice model based on Voronoi tessellation. The model may be applicable in a wide range of sea ice modelling scenarios. Lattice models based on Voronoi tessellation give accurate results in fracture modelling of brittle, inhomogeneous, and/or polycrystalline materials such as concrete and rock. Therefore, our hypothesis is that a similar model might also yield good results in the modelling of sea ice failure. This paper demonstrates that a random lattice model is capable of predicting the deformation of an ice plate on a Winkler foundation. Additionally, it shows a range of other possible applications. Most notably, an application of the model in numerical ice ridge generation is demonstrated.
