TL;DR: In this paper, a finite element method incorporating radiation boundary dampers is employed to solve the corresponding diffraction/radiation boundary value problems, where flexural mode responses are assumed. But the results of both cases compare closely with those obtained by the method of multipoles.

TL;DR: In this paper, two stream function solutions for steady two-dimensional water waves are reviewed and compared with the algorithm developed by Chaplin (1980, Coastal Engineering,3, 179-205).
Abstract: Two stream function solutions for steady two-dimensional water waves are reviewed. The algorithm developed by Dalrymple (1974 , Proc. 6th Conf. Offshore Tech., pp. 843–856) and used by Hudspeth and Slotta (1978 , Proceedings of the American Society of Civil Engineers,104, 319–334) is compared with the algorithm developed by Chaplin (1980 , Coastal Engineering,3, 179–205). By examining more closely the near-breaking wave conditions, it is shown that celerity does not increase monotonically with increasing dimensionless wave steepness. Numerical comparisons between the two algorithms indicate that the Dalrymple algorithm is more accurate for near-breaking waves and requires less computer programming effort. Neither algorithm appears to be able to predict breaking wave conditions as accurately as the Cokelet (1977 , Philosophical Transactions of the Royal Society of London,A286, 183–230) algorithm. Numerical comparisons of the Dalrymple free surface error convergence criteria with the Chaplin significant figures convergence criteria indicate that the free surface error convergence criterion is more consistent for stream function representations.

TL;DR: In this article, a numerical procedure for predicting wave diffraction, wave radiation, and body responses of multiple 3D bodies of arbitrary shape is described, and the boundary value problems are solved numerically by the finite element method (FEM) using a radiation boundary damper approach.
Abstract: A numerical procedure for predicting wave diffraction, wave radiation, and body responses of multiple 3‐D bodies of arbitrary shape is described. Viscous effects are neglected, and the hydrodynamic pressure forces are assumed to be inertially dominated. Within the limits of linear wave theory, the boundary value problems are solved numerically by the finite element method (FEM) using a radiation boundary damper approach. Both permeable boundary dampers and a fictitious bottom boundary element are included in the finite element algorithm in order to treat both permeable boundary problems and deep water wave problems. Numerical results are presented for a variety of structures to illustrate the following features: fictitious bottom boundary, multiple‐structure wave interference, and permeable boundary.

TL;DR: In this article, a numerical procedure is presented for computing wave interference effects on multiple, surface-piercing rigid structures in an ocean of finite depth by the finite element method (FEM).
Abstract: A numerical procedure is presented for computing wave interference effects on multiple, surface‐piercing rigid structures in an ocean of finite depth by the finite element method (FEM). Viscous effects are neglected and hydrodynamic pressure forces are assumed to be inertially dominated. Within the limits of linear wave theory, a scattered wave potential is numerically computed using radiation boundary dampers. Numerical results are presented for a single vertical cylinder and for multiple vertical circular and square cylinders under varying incident wave angles. Comparisons between the FEM results and results available from both analytical and integral equation numerical methods are good. Estimates of the computational savings in CPU realized by the FEM compared to the integral equation method are provided. The favorable numerical comparisons realized by the FEM using radiation boundary dampers coupled with the computational savings in CPU suggest the application of the FEM to more complicated systems of...

TL;DR: The mathematical theory and technology needed to understand the multiple scattering phenomenon is known as multiple scattering, and this book is the first devoted to the subject as mentioned in this paper, and the author covers a variety of techniques, describing first the single-obstacle methods and then extending them to the multiple-obsstacle case.
Abstract: The interaction of waves with obstacles is an everyday phenomenon in science and engineering, arising for example in acoustics, electromagnetism, seismology and hydrodynamics. The mathematical theory and technology needed to understand the phenomenon is known as multiple scattering, and this book is the first devoted to the subject. The author covers a variety of techniques, describing first the single-obstacle methods and then extending them to the multiple-obstacle case. A key ingredient in many of these extensions is an appropriate addition theorem: a coherent, thorough exposition of these theorems is given, and computational and numerical issues around them are explored. The application of these methods to different types of problems is also explained; in particular, sound waves, electromagnetic radiation, waves in solids and water waves. A comprehensive bibliography of some 1400 items rounds off the book, which will be an essential reference on the topic for applied mathematicians, physicists and engineers.

TL;DR: In this article, a review of nonlinear dynamic analysis of membrane structures is presented, focusing on formulation of field equations, wrinkling analysis, fluid/structure interactions, material nonlinearities, and computational methods.
Abstract: Membrane structures have been used since the earliest of times. Until recently, their analysis has relied chiefly on trial and error; however, modern methods of analysis are evolving. The deformations are nearly always of the large rotation and/or strain type and are thus inherently nonlinear. Static analysis can be considered as a special case of the dynamic analysis. This paper is concerned then with reviewing methods of nonlinear dynamic analysis of membrane structures. Two problems of analysis are associated with membrane structures: (i) shape (or form) finding; (ii) response (deformation and/or stress) analysis. Shape finding (ie, determination of the surface geometry given an initial prestress, generation of cutting patterns, etc) is nontrivial but well documented in the literature and is not considered in this paper. In this review attention is instead focused on formulation of field equations, wrinkling analysis, fluid/structure interactions, material nonlinearities, and computational methods.
