The effects of the tapered preform shapes on the final product in cold upset forging are presented. As such, different preform geometries with different upset ratios are considered for the same final part geometry. In addition, the elastic-plastic finite element method is used to examine die filling and determine the flash volume in the final stage for different preform geometries. It is observed that, well-filled final products are obtained when the preform shapes and die cavities are designed according to...

Finite element modeling of stress evolution in quenching process
Doğu, Doruk; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2005)
In this thesis the finite element computer code QUEANA simulating the quenching of axisymetric parts and determining the residual stress state was improved by adding pre- and post-processors. The code was further verified by additional numerical experiments and comparison of the results with commercial software أMARCؤ. The possible applications of this code are optimization of industrial quenching processes by controlling the evolution of internal stresses and dimensional changes.
