Prestressing steel wires are commonly used as reinforcement elements in structures bearing fatigue loads. These wires are obtained by a conforming process called cold drawing, where a progressive reduction of the wire diameter is produced, causing residual stress in the commercial wire. The aim of this paper is to analyze the effect of diverse in-service cyclic loading conditions (cyclic loading and cyclic loading with overload) on such a residual stress field. To achieve this goal, firstly, a numerical simulation of the wire drawing process of a commercial prestressing steel wire was carried out to reveal the residual stress state induced by the manufacture technique. Afterwards, a numerical simulation was performed of the in-service loading conditions of a prestressing steel wire in which the previously calculated residual stress state is included. The analysis of the obtained results shows a significant reduction of the residual stress state of about 50% for common in-service loadings and as high as 90% for certain cases undergoing overloads during cyclic loading. Therefore, an improvement of the mechanical performance of these structural components during their life in-service can be achieved.

“…Gridnev and Gavrilyuk explained the mechanism of cementite dissolution based on the binding energy between carbon and iron atoms in cementite and the interaction energy between carbon atoms and dislocations in the ferrite. They stated that the former is higher than the latter, and hence, carbon atoms leave cementite and spread in the ferrite . Figure d shows the SEM image after annealing at 650 °C for 1 h, which also shows spherical carbides with smaller diameter.…”

The importance of deformed microstructure before transformation‐induced plasticity (TRIP) heat treatment in transformation‐induced plasticity steels was taken into account. The heavily cold‐rolled sheet was annealed at 650 °C for enough time to replace the deformed microstructure with a recrystallized one. It was revealed that the tensile strength, ductility, strain‐hardening capability, and TRIP effect are significantly impaired by the annealing of cold‐rolled sheets. This was explained based on the distribution of the retained austenite phase, strength of ferritic matrix, and the deformation‐induced martensitic transformation.

“…Marder and Bramfitt [34] used the Griffith equation approach in describing the strengthening effects of thermally varied pearlite spacings. Some subsequent studies followed Embury-Fisher's choice of the Hall-Petch equation, most recently by Borchers and Kirchheim [35], while others favored the Griffith equation [36,37]. One persistent finding is that the Hall-Petch equation produces negative or low strength values when 1/ √ d term decreases [34].…”

“…This was based on the ferrite and cementite strength as the base strength. Since then, more possible strengthening mechanisms have been proposed and reviewed [3,35,50]. Some critical issues, like the deformation and fracture of cementite, have been studied further.…”

This study examines the effects of size on the strength of materials, especially on high strength pearlitic steel wires. These wires play a central role in many long span suspension bridges and their design, construction, and maintenance are important for global public safety. In particular, two relationships have been considered to represent strength variation with respect to length parameters: (i) the strength versus inverse square-root and (ii) inverse length equations. In this study, existing data for the strength of high strength pearlitic steel wires is evaluated for the coefficient of determination (R2 values). It is concluded that the data fits into two equations equally well. Thus, the choice between two groups of theories that predict respective relationships must rely on the merit of theoretical developments and assumptions made.
