Abstract
The problem of the motion of a sphere in an ideal incompressible infinite fluid depths under ice cover with nonuniform compression was solved using the method of multipole expansions within the framework of the linear potential theory of waves. researched The hydrodynamic loads acting on the body such as the wave resistance and the lateral and lift forces were studied, and the deflection of the ice cover was analyzed as a function of its thickness, body speed, and the depth of submersion and direction of motion.
