“…In addition to bending load, other load conditions were considered by Sun-Yun Kim and Phill-Seung Lee. 18 They built three elastoplastic models with friction contact to study the conductor response subjected to three loading types: axial-tensile force, transverse load on a pre-tensioned conductor, and bending moment.…”

The present contribution deals with a based FE model treating helically wrapped automotive conductor subjected to pretension force and bending curvature. It is shown that even with low pre-tension force generated by the fixing conditions of the automotive conductor, the bending stiffness varies between two bounds: maximum stiffness for small curvature then from a critical curvature it starts to decrease until reaching a minimum bound independently of friction coefficient and tension force. It can be also, underlined that in addition to the consideration of the inter-layer contact, this elaborated FE model takes into account the friction contact between the same layer wires allowing to the conductor more rigidity. As it can be noticed, this contact mode was neglected in previous literature models.

“…Yu et al [17] examined the contact and lateral load behaviour of a seven-wire steel strand by means of the FE method. In addition, the beam elements were used by some authors [18,19] to investigate the mechanical behaviour of stranded cables, but the refined local stress in the wires cannot be revealed.…”

Refined three-dimensional (3D) finite-element (FE) models of typical aluminium conductor steel reinforced (ACSR) and formed aluminium conductor steel reinforced (FACSR) with structural details to simulate their static and dynamic characteristics are proposed. Taking into account the elastoplastic behaviour of the aluminium wires, the tensile mechanical properties and coupling between tension and torsion of the two types of conductors under tensile loading are numerically investigated. Furthermore, dynamic responses of two transmission lines, in which the refined 3D segment models and equivalent beam models of the two types of conductors are used, after ice-shedding are numerically simulated and the dynamic characteristics of the conductors are analysed. Finally, based on the numerical simulation results, the fatigue lives of the aluminium wires are estimated and the wear between the wires is discussed. It is revealed that taking into account the structural details of the conductors in the strength design of transmission lines is necessary, and the mechanical characteristics of FACSR are better than those of the ACSR in both static and dynamic situations.

“…There are also so-called mixed models utilizing solid and beam FEs at the same time. For instance, the core can be modeled as solid FEs and the wires as beam FEs [ 19 ]. Advanced and detailed 3D models ( Figure 1 a) are typically used to analyze short sections of ropes because they require much work and computational resources.…”

This paper presents research on the bending properties of 3 × 7 19-mm wire rope commonly used in road cable barriers. A total of 19 experimental tests were conducted. In addition, two nonlinear 3D numerical models of the wire rope using beam and solid finite elements were developed. Based on these models, four numerical simulations were carried out. The numerical results were validated against the experimental ones and a very good agreement was obtained. The main result of the research is the determination of the moment–curvature relationship for the wire rope considered. The effect of prestretching on the rope performance is discussed. The numerical results are analyzed in this paper in detail, including the behavior of the wire rope under bending and analyses of the cross-sectional and contact stresses. Suggestions concerning the type of finite element for wire rope modeling are also given. The results can be used, for example, in numerical simulations of crash tests of cable barriers.
