The fracture strengths of the wires are up to 2500 MPa with wire diameters of about 0.5 mm. Since this is a safety relevant component, the aim is to describe the wire rope behavior as precisely as possible by developing a model using the finite element method. A purely geometrical model of the wire rope, as it is used by Judge et al. (2012), is often the standard approach for modeling wire ropes and strands. However, this method does not consider the resulting stresses due to the stranding process. Therefore, a 7-wire strand model, discretized by solid elements, is created using a simplified stranding process. Experimentally measured material data for each wire diameter are used as input data for the model. The validation of the model is also based on experimental test data of various load situations such as tension, bending, or torsion. The focus of this work is to improve the correlation between experimental data and simulation in order to represent the strand as accurately as possible for future fatigue analyses. In contrast to pure geometrical modeling, the influence of the stranding process is considered. © 2021 The Authors. Published by ELSEVIER B.V.

The advantages of wire ropes are their flexibility in combination with high strength in comparison to other traction elements like chains or belts.
