Analysis of Wire Ropes With Internal-Wire-Rope Cores

Stresses in the individual wires of complex wire rope are determined for rope constructions having an internal-wire-rope (IWRC). The ropes may be pulled, twisted, and bent over a sheave or drum. The effects of friction are neglected. Specific results for a 6 × 25 filler-wire IWRC rope that is prevented from twisting indicate that the maximum stresses (exclusive of contact stresses) are typically 1.5 to 3 times as large as the nominal rope stress based on rope load and total metallic area.
