Validity and limitations of linear analytical models for steel wire strands under axial loading, using a 3D FE model ArchiMer
Ghoreishi, S; Messager, T; Cartraud, P; Davies, Peter.
In the field of cable modeling, many models have been proposed to describe the mechanical behavior of simple straight strands under axial loading, and the predictions of these models have been compared to experimental data when available. However, the validity domain of these models has not been evaluated yet because the experimental results reported in the literature are very limited. This problem is addressed here, the results from nine linear elastic models of a 6 + 1 wire single layered strand (simple straight strand) subjected to static axial loads being compared with values from 3D finite element modeling. The analytical models are shown to give satisfactory estimations of the elastic stiffness constants for lay angles below 20 degrees. (C) 2007...

Mathematical Model of a Dynamic Process of Transporting a Bulk Material by Means of a Tube Scraping Conveyor CIGR Journal
Lyashuk, Oleh Leontiyovych; Vovk, Yuriy Yaroslavovych; Sokil, Bohdan; Klendii, Volodymyr; Ivasechko, Roman; Dovbush, Taras.
The results of theoretical studies of simultaneous transporting  the components of feed mixtures along the curvilinear paths of tubular conveyors are presented in this article. The mathematical model of a technological process of moving a bulk material (grain) by means of a cable with a connected scraper is proposed. The model is presented as a system of elastic one-dimensional bodies, which are seamlessly moved by a bulk material. Nonlinear differential equations with partial derivatives that describe the dynamics of horizontal and vertical lines of a tube conveyor under the corresponding boundary conditions are deduced. Based on researches, the technique of determining the technological parameters, which ensure the reduction of energy consumption while...
