Theoretical model for predicting the break-up of ice covers due to wave-ice interaction

摘要: Abstract An approximate solution for wave transmission and reflection between open water a finite viscoelastic ice cover is developed in the present study, which both part are treated as continuum, each governed by its own equation of motion. The interface conditions include matching velocities stresses two continua. In this only modes dispersion relation considered, horizontal boundary approximated mean values. coefficients determined simplified cases to compare with earlier theories. Behaviors resonance obtained pure elastic covers. effect viscosity also investigated According above wave-ice interaction model, stress strain calculated cover. By using failure criterion, break-up condition covers different thickness length under waves sea determined. Finally, dynamic evolution model floe size distribution function marginal zone established. study useful modeling wave-in-ice climate on geophysical scale.
