HYDRODYNAMIC AND MECHANIC RESPONSE OF A FLOATING FLEXIBLE ICE FLOE IN REGULAR WAVES WITH THE ICFD METHOD
Climate change provides for a stronger wave climate and the open water area in this region will increase. The increase in open water area allows for an increase in higher energy surface waves than previously. In addition, human activities are much more complex in this zone, called Marginal Ice Zone,...

Climate change provides for a stronger wave climate and the open water area in this region will increase. The increase in open water area allows for an increase in higher energy surface waves than previously.

This work deals with the development of an efficient simulation environment for the 2D wave-ice interaction on the finite platform LSDYNA. The numerical model based on the coupled ICFD and implicit structural solvers of LS-DYNA. The motion behavior and the mechanical behavior of the ice floe due to the interaction with different waves are investigated. The stronger wave climate in the Marginal Ice Zone intensifies, making the waves more energetic and increasing the wave steepness.
