A Dynamic Ice-structure Interaction Model for Prediction of Ice-induced Vibration
Sea ice crashing against offshore structures can cause strong ice-induced vibration and have a major impact on offshore structural safety and serviceability. This paper describes a numerical method for the prediction of ice-induced vibration when a vertical offshore structure is subjected to the imp...
