On the modelling of complex 3D bulk metal forming processes via the pseudo-concentrations technique. Application to the simulation of the Mannesmann piercing process

摘要

The modelling of complex 3D metal forming processes using the flow formulation, implemented via the pseudo-concentrations technique, requires the development of robust computational strategies for dealing with the velocity and pseudo-concentration boundary conditions in the zone where the blank-tools contact is developed. A new algorithm, designed to fulfil those requirements, is presented in this paper.
