Computational homogenization of an ice sheet with peridynamics

Ice-structure can form and evolve with complex internal arrangements. Factors such as granularity, porosity and crack formation can have a significant impact on the macroscopic structure response. Therefore, a multiscale analysis which applies a homogenization framework on the microscopic level can help capture the overall structure behaviour regarding microscopic structure defects. In this study, a peridynamic representative homogenization analysis is carried out on a semi-infinite ice plate with crack formed along the surface. Periodic boundary condition is applied around the representative volume element. Several homogenization analyses are performed with an increasing crack length, a decrease in corresponding effective elastic modulus is observed within the ice-structure.
