OC6 Phase Ia: CFD Simulations of the Free-Decay Motion of the DeepCwind Semisubmersible
Energies, 2022 Currently, the design of floating offshore wind systems is primarily based on mid-fidelity models with empirical drag forces. The tuning of the model coefficients requires data from either experiments or high-fidelity simulations.

Coefficient of Restitution Interpreted as Damping in Vibroimpact [PDF]
Journal of Applied Mechanics, 1975 During impact the relative motion of two bodies is often taken to be simply represented as half of a damped sine wave, according to the Kelvin-Voigt model. This is shown to be logically untenable, for it indicates that the bodies must exert tension on one another just before separating.

Computation of Rayleigh damping coefficient of a rectangular submerged floating tunnel (SFT)
SN Applied Sciences, 2020 The dynamic behaviors of the submerged floating tunnel, a buoyant structure of high slenderness, are a matter of concern since it is surrounded by the huge hazardous effects called hydrodynamic, seismic and functional action.

Material Damping in Dynamic Analysis of Structures (With LIRA-SAPR Program)
Civil and Environmental Engineering, 2020 The purpose of this paper is to justify that it is necessary to take account of physical and mechanical properties of soil and different materials of erected structure for damping vibrations in dynamic loads; to suggest tools for modelling the damping ...

Damping Seiches and Estimate of Damping, Linear Frictional Coefficients
Japanese Journal of Limnology (Rikusuigaku Zasshi), 1979 The frictional effect on the period of surface seiches in Lake Biwa has been discussed by TAKAHASHI and NAMEKAWA (1931). They concluded that the seiches of the longest period of 4 hours in Lake Biwa may be considered as a bay oscillation in the southern basin, and the difference of the period between the observed and theoretical one is due to an ...
