The nonlinear dynamic analysis of cable and membrane structures
is presented in this study. Attention is given to the nonlinearities
arising from large displacements, from nonlinear stress-strain
relationships and from nonconservative loadings.
The finite element method is used to model the cables and
membranes. Curvilinear geometries of the elements are...
Cables used in the ocean are often constructed of helically wound
wires or strands. Tension in the cable induces torque and/or rotation
about its longitudinal axis. A method is presented to determine the
tension, torque, location and angular orientation of points on the
cable centerline, using a shooting method algorithm...
Time-domain models were developed to predict the response of a tethered buoy
subject to hydrodynamic loadings. A coupled analysis of the interaction of a buoy and
its mooring is included and three-dimensional response is assumed. External loadings
include hydrodynamic forces, tethers tensions, wind loadings and the weight of both
cable...
