TL;DR: In this article, the metal flow in open-die forging is analyzed through a number of upper-bound solutions and the basis of an on-line analytical modeling system, together with experimental correlation and a planning system, is presented to produce bar profile features.

TL;DR: In this paper, a simple kinematically-admissible velocity field is proposed to determine the final-stage extrusion load and average length of the extruded products in the square die extrusion of non-axisymmetric bars from round billets.
