Calculating the mechanical stresses in cable elements is essential for analyzing the cable’s mechanical properties and fatigue properties. This paper derives numerical calculations of the stresses in helical cable elements for cables subject to bending- and twisting loads. The numerical calculations are compared to analytical approximations from the scientific literature. The former gives higher accuracy, and discloses behaviors and coupling effects that are not captured by the latter. These favorable properties combined with easy implementation, no risk of convergence issues, and very short CPU time, make the numerical calculations a very attractive alternative to the analytical approximations.
