Modeling the Mechanical Energy Budget of the Beaufort Sea Ice Cover.
The mechanical energy balance for the sea ice cover of the Beaufort Sea portion of the Arctic Ocean has been used to evaluate a parameter study on the strength of a plastic sea ice model. The results of this study show that a hardening plastic model with a diamond shaped yield surface and a compress...

The mechanical energy balance for the sea ice cover of the Beaufort Sea portion of the Arctic Ocean has been used to evaluate a parameter study on the strength of a plastic sea ice model.

The mechanical energy (power) budget utilizing a hardening plastic model was examined for a seventeen day period during the winter of 1976.
