Numerical investigation on equal channel angular extrusion process of polymers

The goal of this work is to numerically show by using finite element method the influence of key factors on the mechanical response of a workpiece in equal channel angular extrusion (ECAE) process. Various geometrical parameters (channel angle, outer corner angle and inner radius) and material properties were considered in the numerical calculations with a view to the use of the process to polymers.
