Numerical and physical modelling of cold forging of bevel gears
TLDR
In this article, finite element (FE) based numerical modeling and physical modelling with plasticine are presented as process design tools in cold forging of bevel gears, and the results from the process simulation are then used as load input data for a punch stress analysis.About:

Application of the 2D finite element method to simulation of cold-forging processes
Taylan Altan,Markus Knoerr +1 more
TL;DR: Deform as mentioned in this paper is a two-dimensional computer code developed by Battelle Columbus Laboratories, which is used extensively by non-aerospace forgers for the investigation of die fill, defect analysis and prevention, as well as for the prediction of part properties.

Numerical process simulation for tool and process design in bulk metal forming
Taylan Altan,Victor Vazquez +1 more
TL;DR: Numerical simulation of bulk metal forming processes is increasingly applied to eliminate forming defects, predict and optimize process variables, and predict stresses in dies for preventing premature die failure as mentioned in this paper.

Increasing tool life in cold forging through advanced design and tool manufacturing techniques
TL;DR: In this paper, results of two investigations concerned with the evaluation and prediction of fatigue failure and the improvement of tool service life in cold forging are presented, which clearly indicate the value of performing a tool stress analysis during the process and tool design phase.
