X-Catenary Cable Element
The nonlinear cable element has 2 nodes and total 6 DOF. Its can resist only tensile load i.e. it has no strength and stiffness in the compressive direction.
The stiffness of the catenary cavle element is dependent on its weight, length and the tension force itself. The nonlinear force-displacement relationship was included to take into account the sag effect that is importance in the practical cable structures.
The multi-linear material behavior was also incuded into the element formulation, thus the element can be used in geometric and material nonlinear analysis of the cable structures such as suspension bridges.
T is the line tension, A is the cross-section area of the line, E represents the elasticity modulus, F and D correspond to the drag or mean hydrodynamic forces both normal and tangential direction, respectively,
The Xcable-Mooring is provided fot helping users to generate true profile of the mooring line whith seabed contract. This line will give begin and end position of seabed contract.
A three dimensional 2-node frame element can be used for the linear and nonlinear dynamic analysis of 3-D offshore framed structures.
