On modeling the metal forming processes

Abstract

The modelling process of the bulk metal forming, being characteristic of the axysymetric element family is done in this paper. Three methods are used: Finite Element Method (FEM), Upper Bound Elemental Technique (UBET) and Plan Experimental Method (PEM). The changes of the force and piecework geometry, given in the parallel diagram, have been followed. Based on the results obtained it has been concluded that the methods mentioned may be relatively well applied to the forming analysis of the given process.
