Nonlinear Analytical Model for Wire Strands

Chunlei Yu, Wenguang Jiang, Lijuan Yan, Jianying Cui, Liping Zhu
A nonlinear analytical wire strand model under axial tensile load has been developed in this paper. The model extends Costello's elastic strand model by taking into account of the effect of contact deformation between contacting wires. Hertz contact theory is adopted to establish the relationship between...
