Subsequent drawing of anisotropic viscous-plastic material

Abstract

The proportions for stress computation at the subsequent drawing of anisotropic billet under conditions of viscoplasticity are obtained. The equilibrium equations in stresses and a linear condition of fluidity are used. The impact of billet bending upon radial areas of a matrix and clamping and also friction is taken into account. The assessment of billet material damageability is carried out.
