The nonlinear dynamic analysis of cable and cable-large
body systems subject to both deterministic and non-deterministic
loading is presented in this study. Nonlinearities
occur due to large displacements, material nonlinearity,
lack of stiffness in compression, and the non-conservative
fluid loading.
A finite element model is used to model the cable...
Two types of linear random wave simulation methods are investigated;
viz., (1) Deterministic Spectral Amplitude (DSA) and (2) Nondeterministic
Spectral Amplitude (NSA). These linear simulations are extended to
second-order in a perturbation expansion in the frequency domain by
utilizing a Fast Fourier Transform (FFT).
The nonlinear interaction matrix for waves...
A three dimensional finite element analysis is developed which
is capable of simulating the coupled static and dynamic behavior of
compliant ocean structures. Nonlinearities which result from large-deflection,
reduced or zero stiffness in compression, and the nonconservative
fluid loading are considered. The spatial variation of
fluid loading is also addressed....
