Abstract
We examined whether surface flaw on wire rods grow or are removed during drawing by finite element method (FEM) analysis and experiments. The deformation behavior of V-shaped, concave, and U-shaped transversal flaws were observed upon repeated drawing. We clarified the conditions under which these transversal flaws are removed in order to achieve a surface condition similar to that of the area without flaw. The effects of the angle, width and depth of surface flaw on their removability were also clarified.
