Abstract

It is important to understand the sequential ice load development on ships during ice-structure interaction when the ship structure may not be a planar surface. Laboratory tests were performed based on the assumption that the shape of the structure is perfectly flat or slightly convex/surfaces in general. This study plans to consider the cases where the shape of the structure is a wedge or conical. Obtained results were compared with flat surface test conditions. Trends of force-displacement, pressure-area curve, contact area and changes of pressure within the contact region were evaluated. Pressure distribution on non-planar surface showed a significant difference and induced a higher ice load compared to a flat surface.
