Digitized edition from print [produced by Defence Research and Development Canada]. Includes bibliographical references (pages 57-58). "A method of generating the added fluid mass matrix for use in dynamic analyses of submerged structures is presented. This method uses a distribution of panel singularities in the form of sources or dipoles on the fluid/structure interface to represent the velocity potential in the fluid surrounding the structure. The fluid added mass matrix is calculated by relating the pressure field in the fluid to the structure surface accelerations via the Euler equation and the assumptions of potential flow theory. Based on the results of a variety of investigations of computational performance, convergence and dynamic response involving floating cylinders, ship hulls, and propeller blades, the surface panel method is shown to provide an effective alternative to the finite element added mass matrix system. The surface panel program suite has been developed in a form compatible with an existing finite element analysis package, although the dependence on the particular solution system is not large"--Abstract, page ii.
