Effect of Parameters on the Mechanical Behavior of Core Strands: Experimental, Numerical and Statistical Study

The cables are widely used in mechanical, electrical and civil engineering applications, as they are flexible and highly resistant. In this paper, the behavior of the elastic limit of straight central core strands is studied. In this study, we focus on the elastic limit’s behavior of straight central core strands. That is, we investigate 27 cores with different configurations. They generally consist of 7 wires (1+6) belonging to wire ropes of type 19x7 subjected to static axial loads. The numerical study is performed using finite element method (FEM). The main results are compared with experimental data. Finally, to determinate the impact of three parameters: the basic material constituting the strands, the winding angle of wires and the diameter of strands on the yield strength of the core strands, we apply a design of experiments (DOE) analysis by YATES’ method.
