Abstract
In this paper, a finite element model of a single strand cable is presented. This model allows for the study of all the possible interwire motions. It is used to analyse the role of the contact conditions in pure axial loading and in axial loading combined with bending. The model proves to be reliable compared with experimental and theoretical data when available. It appears that the interwire pivoting has a strong influence on the cable response in axial loading whereas it is interwire slippage which is pre dominant when bending is present. Moreover, it is shown that pivoting can be considered as free. At last, the influence of bending on the tension in each wire of an axially preloaded strand is investigated.
