Hydroelasticity of Ships

Shows how the wave responses of a ship can be calculated using linear dynamics.

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.

A ship is a flexible structure that moves bodily and distorts when it encounters waves. This book, however, shows how the wave responses of a ship can be calculated using linear dynamics. The authors integrate the techniques of structural theory, hydrodynamics, oceanography and statistical theory in their systematic use of dynamical theory. The principles apply to offshore structures as well.
