OVERHEAD ELECTRICAL CONDUCTORS IN BENDING : A SEMI-CONTINUOUS MODEL

As indicated in the review by Cardou & Jolicoeur (1997), and depending on the application, a helically stranded system may be modelled using a semi-continuous approach whereby each layer is replaced by a continuous helical orthotropic material. For those able to read Russian, this approach is presented in a paper by Danilin & Al. specifically oriented towards Overhead Electrical Conductor mechanics: “Modelling of Deformation of Wire Spiral Structures” published in the PNRPU Mechanics Bulletin (2015, No 4, pp. 72-93). An abstract in English is available online at:  http://vestnik.pstu.ru/mechanics/archives/?id=&folder_id=5049 . Needless to say, this approach is not appropriate for fatigue problems where contact mechanics play a primary role.
