Cold-drawn steel wires have the excellent mechanical properties of strength and toughness and are widely used in prestressed concrete structures. During cold-drawn operations residual stresses are generated in steel wires. In this paper, by the residual stress distribution from the finite element analysis (FEA), a weight function method (WFM) has been used to evaluate the effective stress intensity factors (SIFs) for cracked cold-drawn steel wires under tensile loading. The calculation results
