Anisotropic Plasticity Constitutive Law for Sea Ice

My long term goal is to develop sea ice dynamics models that describe behavior on kilometer scales and larger, and to base these models on the smaller scale physical processes known to control leading, rafting, and ridging. My three-year contract has five tasks: (1) complete development of the model...

Description
Summary:My long term goal is to develop sea ice dynamics models that describe behavior on kilometer scales and larger, and to base these models on the smaller scale physical processes known to control leading, rafting, and ridging. My three-year contract has five tasks: (1) complete development of the model and test it with 0d calculations, (2) incorporate the model into a 2d numerical code and test its performance by comparing behavior with observed behavior during the SIMI Main Experiment and at other times, (3) extend my ambient noise model by developing a process-based noise source for ridging and to relate the noise-generating model to ice mechanical behavior, (4) help transfer the new models into fleet systems such as PIPS, and (5) publish the results.
