Abstract EN
The increasing marine activities in Arctic area have brought growing interest in ship-iceberg collision study.
The purpose of this paper is to study the iceberg geometry shape effect on the collision process.
In order to estimate the sensitivity parameter, five different geometry iceberg models and two iceberg material models are adopted in the analysis.
The FEM numerical simulation is used to predict the scenario and the related responses.
The simulation results including energy dissipation and impact force are investigated and compared.
It is shown that the collision process and energy dissipation are more sensitive to iceberg local shape than other factors when the elastic-plastic iceberg material model is applied.
The blunt iceberg models act rigidly while the sharp ones crush easily during the simulation process.
With respect to the crushable foam iceberg material model, the iceberg geometry has relatively small influence on the collision process.
The spherical iceberg model shows the most rigidity for both iceberg material models and should be paid the most attention for ice-resist design for ships.
