Abstract
Residual stresses developed during wire drawing
influence the mechanical behavior and durability of steel
wires used for prestressed concrete structures, particularly
the shape of the stress–strain curve, stress relaxation losses, fatigue life, and environmental cracking susceptibility. The availability of general purpose finite element analysis tools and powerful diffraction techniques (X-rays and neutrons) has made it possible to predict and measure accurately residual stress fields in cold-drawn steel wires. Work carried out in this field in the past decade, shows the prospects and limitations of residual stress measurement, how the stress relaxation losses and environmentally-assisted cracking are
correlated with the profile of residual stresses and how the
performance of steel wires can be improved by modifying
such a stress profile
