Effect of anisotropic yield criterion on springback in plane strain pure bending

Abstract

The plastic anisotropy is one of various material representations that significantly affects springback simulations. In the present paper, the effect of plastic anisotropy of springback in plane strain pure bending is studied by means of an exact semi-analytical solution. To take into account anisotropy it is used the yield criterion and the constitutive equations for the orthotropic material with consideration of the crystal lattice constants and parameters of the crystallographic texture.
