This study aimed to evaluate the effect of non-metallic inclusions on ductile damage during the multi-pass dry wire drawing process for manufacturing steel cords for tire reinforcement. The multi-pass design for the high-carbon (0.92-wt%C) steel-cord wire drawing process was carried out using an isothermal pass schedule to achieve a uniform wire temperature. The proposed drawing process reduced the wire diameter from 3.550 to 1.999 mm. The spherical non-metallic inclusion of Al2O3 was located at the center of a steel wire rod. The influence of the Al2O3 inclusion size on the effective strain and ductile damage during the ninth pass dry drawing process was investigated using finite element analysis. As the size of the Al2O3 inclusions increased, the effective strain, hydrostatic stress, and critical damage values inside the wire in contact with the inclusions increased as well.

This study aimed to evaluate the effect of non-metallic inclusions on ductile damage during the multi-pass dry wire drawing process for manufacturing steel cords for tire reinforcement.

The proposed drawing process reduced the wire diameter from 3.550 to 1.999 mm. The spherical non-metallic inclusion of Al2O3 was located at the center of a steel wire rod. The influence of the Al2O3 inclusion size on the effective strain and ductile damage during the ninth pass dry drawing process was investigated using finite element analysis. As the size of the Al2O3 inclusions increased, the effective strain, hydrostatic stress, and critical damage values inside the wire in contact with the inclusions increased as well.
