TL;DR: In this article, a new method of modeling material behavior which accounts for the dynamic metallurgical processes occurring during hot deformation is presented, which considers the workpiece as a dissipator of power in the total processing system and evaluates the dissipated power co-contentJ = ∫o σ e ⋅dσ from the constitutive equation relating the strain rate (e) to the flow stress (σ).

CAD/CAM of streamlined extrusion dies
TL;DR: In this article, a CAD/CAM package is developed for the design of streamlined dies for the extrusion of difficult-to-extrude metal-matrix composite materials and P/M alloys.
