A mechanical model for compaction of strands for wire ropes

Steel wire ropes are used for numerous industrial applications such as ships, elevators, cranes and bridges. A rope consists of thin, steel wires its geometrical construction can be explained in two steps. First, several wrapped together a helical shape called strand. Second, strands to form the final rope. In most cases, each strand is compacted before they Compaction generally reduces contact stresses thereby, extends ropes’ service life. Not many models have been proposed predict compaction process influence on strand’s mechanical behavior during service. This contribution proposes computationally efficient approach that elastoplastic models. The first model, describing process, 2D plane strain nature therefore fast. Subsequently, geometry plastic variables predicted by model generate initial state 3D subsequently describe (we limit ourselves tension). results approach, with without mapping variables, compared experimental measurements compaction. investigated real world strands.
