INITIAL VALUE PROBLEM FOR THE MOTION OF A BODY IN AN UNDULATING SEA. I. FIXED EQUILIBRIUM POSITION
Abstract
By modification of a method first introduced by Volterra for the solution of certain initial-value problems for water waves, integro-differential equations are derived for the motion of a body floating in a wavy sea and oscillating about an equilibrium position, given its initial position and velocity and the initial configuration and velocity of the field. In addition, it is shown how Cummins' decomposition of the hydrodynamic force and moment resulting from the 'forced motion' fits naturally into the present treatment and how Haskind's relations between the force and moment caused by diffracted waves and by forced waves can be extended to the situation considered here.
