“…On the other hand, stranded cable damping source comes mainly from the sliding between wires during flexural vibrations [23]. The stick-slip frictional behaviour of strand cables was first described by Hardy [24] and extended by Goudreau et al [25] which is modelled using classic Amontons-Coulomb friction law. More detailed models assess the stick-slip behaviour of each wire of the strand to account for the non-linear section bending response of the cable cross section [26].…”

Efficient and accurate modelling of mooring and cable systems for Floating Offshore Wind Turbines are a key factor in the coupled dynamic analysis for the realistic assessment of such floating structures. In order to improve the modelling of the mooring and cable systems, a new extension of the slender rod finite element model proposed by Garret with the inclusion of rheological damping is presented. The model takes into account the damping produced for the rod material in both the axial and the bending forces. Derivation of the axial and bending damping forces is presented and assessed in terms of the critical damping. The implementation of the model is presented and tested through three verification simulations and two validation examples, which show a good agreement when comparing with experimental results and prove the capacity and robustness of the model.

“…This, in turn, plays a key role in assessing the vibration level of lightly damped structures, such as suspended cables (e.g. : Goudreau et al, 1998;Rawlins, 2009), as well as the performance of damping and base isolation devices (e.g. : Gerges, 2008; Sauter and Hagedorn, 2002).…”

Aim of the present work is to build a link between a structural theory for large-scale analyses of three-dimensional cable structures undergoing, in general, large displacements and rotations, and a refined mechanical description of metallic strands, fully accounting for their composite nature and hysteretic bending behavior. A new formulation for metallic strands is presented. The strand overall mechanical behavior is modeled according to the Euler-Bernoulli beam theory. A constitutive law relating the cross sectional generalized stresses and strains of the adopted structural model is obtained by summing over the individual contributions of wires. Each wire in the strand is individually modeled as a curved thin rod. Kinematic equations are proposed to relate the wire generalized strain variables to those of the strand cross section. The equilibrium of the individual wires is analyzed under the hypothesis of radial contact between adjacent layers taking, most notably, also into account the effects due to the residual radial contact forces induced by the strand manufacturing process. Deformations of contact surfaces are neglected and friction is accounted for, through the Amontons-Coulomb law, in the study of the stick-slip conditions. The proposed sectional model accounts for some distinctive characteristic aspects of wire ropes, such as the coupling between axial force and torque and the non-linear, and non-holonomic, relation between bending moment and curvature, which is a consequence of sliding of wires. The performance of the proposed formulation is assessed with reference to well-documented physical tests and established analytical formulations. Moreover, the role of the residual contact forces due to the stranding process, on the bending behavior of a typical multi-layer strand is assessed

“…Relative displacements between the wire centerline (which will be denoted in the following as u t ) and the core, however, are present also in the no-sliding regime because of the tangential compliance of the contact surface. Goudreau et al [12] studied the tangential compliance mechanism between the external wires and the core of a strand by exploiting the solution of the Hertzian contact problem for two parallel cylinders, made of the same material and pressed together. Accordingly, they introduced a non-linear relation between the relative displacement u t and the tangential force per unit length T, herein re-stated as follows:…”

Abstract. A new formulation to model the mechanical response of metallic strands undergoing a combination of axial load and planar bending is developed. Each wire of the strand is modeled as an elastic curved thin rod. A kinematic model is then introduced to relate the generalized strain variables of the strand to those of the wires. The stress-strain state of the wires is evaluated starting from the analysis of the internal contact conditions. Friction is modeled through the classic Amontons-Coulomb law and the elastic tangential compliance of contact patches is accounted for. A non-holonomic material constitutive law in terms of
