Abstract: We investigate the response of a nonlinear small-body ocean-mooring system excited by finite-amplitude waves. The system is characterized by a coupled geometrically nonlinear restoring force defined ...

Abstract: We investigate the nonlinear dynamics and stability of a rotating system with an electromagnetic noncontact eddy-current damper. The damper is modeled by a thin nonmagnetic disk that is translating ...

Abstract: Finite amplitude dynamics of ships in head seas due to parametric instabilities is a subject of renewed interest with an increasing demand of operation in severe and variable environmental ...

Abstract: We combine an averaging procedure with a Hilbert transform-based algorithm for parameter estimation of a nonlinear ocean system roll model. System backbone curves obtained from data are compared ...

Abstract: This paper focuses on a boundary value problem governing the equilibrium of a slender cable subject to thrust, torsion, and gravity. In the absence of field (gravity) loading, this boundary ...

Abstract: In this paper, we develop and implement a nonlinear model based procedure for the estimation of rigid-body motion via an indirect measurement of an elastic appendage. We demonstrate the procedure ...

Abstract: An intricate universal superstructure in bifurcation sets and routes to chaos of a nonlinear moored ocean system subjected to monochromatic wave excitations are investigated analytically and demonstrated numerically in ...

Abstract: We introduce and demonstrate the applicability of a parameter identification algorithm based on the Hilbert transform to nonlinear ocean mooring systems. The mooring dynamical system consists of ...

Abstract: A spatial string model incorporating a nonlinear (and nonconservative) material law is proposed using finite deformation continuum mechanics. The resulting model is shown to reduce to the classical ...
