Elastic-plastic responses of ship plates under ice impact loading
Objectives Arctic channel plays an increasingly significant role in ocean transportation. Polar ships inevitably encounter ice floe impacts in the Arctic channel. These impacts may cause some permanent structural deformations, which will result in some negative effects on their work performance. The...
