The proposed model addresses the limitations of existing analytical methods, such as equilibrium and lower-bound approaches, by considering height reduction, relative density increments, and varying die-workpiece interactions simultaneously. The model’s predictions align closely with experimental results, demonstrating its reliability and accuracy. This research paves the way for the development of industrial-grade software tools, offering manufacturers a competitive edge by improving process predictability and reducing dependence on computationally intensive methods like the Finite Element Approach.Refference:
