Finite element analysis of prestressed die set in cold forging

An application-oriented finite-element approach to forging die structural analysis is presented in this paper. The die set structural analysis problem is formulated as a contact problem with both shrink fit and preloaded clamping considered, solved iteratively by a varying penalty method. The loadin...

Beschreibung
Zusammenfassung:	An application-oriented finite-element approach to forging die structural analysis is presented in this paper. The die set structural analysis problem is formulated as a contact problem with both shrink fit and preloaded clamping considered, solved iteratively by a varying penalty method. The loading condition is extracted automatically from forging simulation. A predicted solution is compared with analytical one and two application examples are given, which show the applicability of the approach.
