ABSTRACT = {In this study, a numerical method was developed based on peridynamics to
determine the ice loads for a ship navigating in level ice. Convergence analysis of threedimensional
ice specimen with tensile and compression loading are carried out first. The
effects of ice thickness, sailing speed, and ice properties on the mean ice loads were also
investigated. It is observed that the ice fragments resulting from the icebreaking process
will interact with one another as well as with the water and ship hull. The ice fragments
may rotate, collide, or slide along the ship hull, and these ice fragments will eventually
drift away from the ship. The key characteristics of the icebreaking process can be obtained
using the peridynamic model such as the dynamic generation of cracks in the ice sheet,
propagation and accumulation of ice fragments, as well as collision, rotation, and sliding
of the ice fragments along the ship hull. The simulation results obtained for the ice loads
and icebreaking process were validated against those determined from the Lindqvist
empirical formula and there is good agreement between the results.},
