THE DEVELOPMENT OF IDEAS CONCERNING ICE SHIP STRENGTH

The paper describes the evolution in USSR of methods for the determination of ice loads on vessels navigating in arctic waters, in order to select the most efficient ice strengthening. Full scale trials with ice-strengthened vessels and icebreakers operating in ice conditions are described and discussed, and the ice loads evaluated. Mathematical expressions for ice breaking force, maximum shear force of ice, and impact impulse when colliding with ice are developed. Order from NSFI as No. 19504.
