Determination of the Material Properties of an Anisotropic Metal Wire

Abstract The material properties of cold-drawn wire are not the same in the drawing direction as in the radial direction, due to texture development. The anisotropy usually remains in the material after annealing and has therefore an effect on subsequent forming operations. This article describes a practical way of determining the parameters in the Hill anisotropic yield criterion for a thin wire by the means of compression tests and inverse simulation.
