This $288,448 Project Grant was awarded by the National Science Foundation's (NSF) Division of Polar Programs (CFDA 47.078) to Oregon State University (OSU) on June 15, 2025. The grant supports the development and validation of multiscale numerical models that link the micromechanics of sea ice to its macroscopic behavior under various environmental conditions. The research combines advanced experimental and computational techniques, including high-resolution X-ray computed tomography (CT) imaging to analyze sea ice's internal structure, discrete element modeling (DEM) to simulate microscale interactions and failure mechanisms, and hybrid FEM-DEM simulations to integrate micro- and macroscale behaviors. Laboratory experiments and numerical simulations will be used to investigate key phenomena, such as sea ice deformation, cracking, and floe-scale interactions. The validated models will provide new tools for understanding sea ice dynamics, supporting Arctic engineering, and addressing challenges posed by evolving ice conditions. No sub-awards are planned for this grant.
