Fig. 14From: Cross section shape optimization of wire strands subjected to purely tensile loads using a reduced helical modelInfluence of a perturbation of the geometrical parameter \(\rho _1\). Below the plot, the corresponding resulting cross sections are shown. The change of \(\Delta \rho _1\) has been scaled for visualization purposes, on the left for negative \(\Delta \rho _1\), on the right for positive variationsBack to article page
