A Study on the Shearing Strength and Adhesive Strength of Sea Ice

摘要

In designing an offshore structure in an ice-covered sea area, understanding the ice load exerted by sea ice is necessary. To determine the adhesive and the shearing strengths of sea ice and their relation to the bending strength, we used the first-year ice at Notoro Lagoon. To define the stress distribution of the shearing strength of the test specimen, we used the finite element method elastic stress analysis. The adhesive strength test specimen kept outdoors separated at the attached surface, yielding an adhesive strength of 50 kPa. The shearing strength test specimen ruptured in bending. The shearing strength was found to be between 0.2 and 0.3 MPa.
