Abstract

A planar finite element model is created for modeling the equal channel angular pressing (ECAP) processing of copper, by which the technological parameters can be determined for different initial parameters of the ECAP process. The structure of the model is described, as well as the extraction of the force and work data, furthermore results for the effect of the initial parameters, e.g. the friction and the frictional model on the extrusion force and work characteristics are shown.

Key words: equal channel angular pressing, extrusion, friction model, finite element simulation
