The Finite Cover Method (FCM) is applied for the plate bending problem for the analysis of progressive failure of sea level ice. The method to introduce discrete plane in Finite Cover Method to model the failure of ice is shown with assumed stress elements to avoid the shear locking in Mindlin plate, and good accuracy is obtained for the case of large aspect ratio. We simulated the process of ice crack by an ice breaking vessel with calculator, using double nodes definition, contact problem, and above method. And we calculated the icebreaking resistance.
