Hydroelasticity of Ships [Paperback]

Shows how the wave responses of a ship can be calculated using linear dynamics.Explains the theory behind the bending and twisting of ships and shows how to work out the behavior of a hull in heavy seas with the aid of a computer.Explains the theory behind the bending and twisting of ships and shows how to work out the behavior of a hull in heavy seas with the aid of a computer.A ship is a flexible structure that moves bodily and distorts when it encounters waves. This behaviour is potentially dangerous and it must therefore be predicted as a necessary part of ship design. Hitherto the theory of ship structures has had to employ simplifying assumptions, and the dynamical theory has been founded largely on the assumption of rigidity. This book, however, shows how the wave responses of a ship can be calculated using linear dynamics. This general treatment adapts the techniques of structural theory, hydrodynamics, oceanography and statistical theory to the needs of naval architecture. In a radically new departure the authors unify these various techniques in their systematic use of dynamical theory. The principles are applicable to offshore structures in general as well as to ships.Preface; 1. Ship response; 2. The dry hull; 3. More accurate analysis of hull dynamics; 4.
