COMPUTER APPLICATION TO THE VISIOPLASTICITY METHOD.

Abstract

Procedures for using a computer for the complete solution to plane strain as well as axisymmetric deformation problems have been developed. The velocity, strain rate, total effective strain, and stress distributions were obtained for two commercially pure lead specimens extruded in a forward extrusion process using white lead in oil as a lubricant. The axisymmetric extrusion was carried out at a speed of 1/8 in./min through a conical die having a 45 degrees half cone angle with a 2:1 extrusion ratio, and the plane-strain extrusion through a tapered die having a 45 degrees half taper angle with a 1.66:1 extrusion ratio.
