A concise finite element model for simple wire strand under pure bending is presented in this paper. Accurate bending symmetric boundary condition has been developed and applied to the periodic artificial cross-sectional end boundaries of the wire strand finite element model. To achieve better analysis accuracy, full three-dimensional solid elements were used for structural discretization. For the global behaviour of the wire strand, i.e. bending moment vs. bending curvature, the finite element results showed good agreement with the analytical elastic strand model of Costello (Theory of wire rope, 2nd ed. New York: Springer-Verlag; 1997) in elastic loading regime. Furthermore, the finite element model can predict the detailed progressive nonlinear plastic behaviour of the wire strand.
