Definition
Flexural strength of sea ice is the maximum bending stress that the sea-ice material can take. This definition is drawn from the traditional material mechanics. Once the sea-ice strength is surpassed, the failure and fracture of sea-ice plate are followed. The flexural strength is closely connected with many natural phenomenon and engineering properties of sea ice. For example, the breakup, rafting, and ridge-building are often observed in polar area and seasonal ice-covered region, when the ice covers are under the actions of wave, current, and wind. In the cold region, the jacket platform with ice-breaking cones, artificial island, slope protection, and ice breaker suffer from the collision of the ice cover. These situations generally cause the bending failure mode of sea ice, and the ice loads of the structures are subsequently determined by the flexural strength.
In essence, the flexural strength of sea ice is induced by the momentum...
