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.
