“…In the past years, different linear analytical models were presented to predict the mechanical behaviors of the spiral strands [1][2][3][4][5][6], but the precision of the models are very limited due to the simplifications used. In these models, some influencing factors are ignored, such as the complex helical configuration, Poisson's ratio effect, symmetric stiffness matrix, torsion, bending, contact, friction and local plastic yielding of wire ropes.…”

“…This formulation leads to a set of non-linear equations. A more recent paper by Philips and Costello (1985) presents a solution of the same theory applied to wire rope with internal wire rope cores. Kumar and Cochran (1987) have developed a linearized form of this theory, leading to a closed-form expression for axial stiffness coefficients.…”

In part I of this study it was shown that, to model synthetic fiber ropes, two scale transition models can be used in sequence. The first model (continuum model) has been presented in the part I and the present paper examines the behavior of a fibrous structure consisting of 6 helicoidal strands around a central core (1 + 6 structure). An analytical model will be presented which enables the global elastic behavior of such a cable under tension-torsion loading to be predicted. In this model, first, the core and the strands are described as Kirchhoff-Love beams and then the traction-torsion coupling behavior is taken into account for both of them. By modeling the contact conditions between the strands and the core, with certain assumptions, it is possible to describe the behavior of the cable section as a function of the degrees of freedom of the core. The behavior of the cable can thus be deduced from the tension-torsion coupling behavior of its constituents. Tensile tests have been performed on the core, the strands and then on a full scale 205 ton failure load cable. Finally, predicted stiffness from the analytical models is compared to the test results.

The theoretical analysis of a large-diameter stranded wire rope with fibre core, using results from a previously reported orthotropic sheet model for analysing the behaviour of its constituent helical strands, is reported. The present model is (unlike previously available theories for stranded wire ropes) capable of catering for the effects of interwire friction and contact deformations.The proposed theory provides a fairly simple means of obtaining the upper (no-slip) and lower (full-slip) bounds to rope effective stiffness coefficients under axial/torsional coupling with encouraging correlations found between the theoretical predictions for the axial stiffness under full-slip conditions and experimental data for some realistic stranded wire ropes with fibre cores.
