Analytical and finite element modelling of the elastic–plastic behaviour of metallic strands under axial–torsional loads
journal contribution
posted on 2017-07-28, 13:49 authored by Francesco Foti, Alessandro de Luca di RosetoIn this work a new formulation for modelling the elastic–plastic behaviour of metallic strands subjected to axial–torsional loads is presented. Simple and accurate cross sectional constitutive equations a rederived, fully accounting for the evolution of plastic deformations in the wires, starting from a description of the internal structure of the strand. The proposed approach is suitable both for straightforward analytical calculations as well as for implementation into finite elements for the large-scale structural analyses of cable structures. A full three-dimensional(3D) finite element(FE) model, based on a parametric description of the strand internal geometry, is also developed. The results of both the FE model
and the analytical formulation are validated with reference to a well-documented physical testing
campaign and a well-established linearly elastic literature model. Additional analyses are then performed to carefully assess the validity of the proposed mechanical formulation, for a wide range of strand construction parameters, by means of systematic comparisons against the results of the 3DFE modeland of a recent linearly elastic literature model.
