Coupled Axial-Torsion Cross Section

The cross section is used to model axisymmetric parts of the slender system which have a coupled axial / torsion stiffness properties and / or bending / curvature hysteresis effects. The cross section is especially useful for modelling cables with armour layers.

The hydrodynamic load models

  • Morison’s generalized Equation

  • Morison partly submerged cross sections

  • MacCamy Fuchs

  • Potential flow

  • Time domain VIV loads

  • No hydrodynamic loads

are available for Coupled axial-torsion Cross Section. For details, please see Hydrodynamic load models.
