Process Metamorphosis and On-Line FEM- A Novel Approach for Fast Analysis in Engineering

Abstract

This paper introduces the new concept – on-line FE model, as applied to metal rolling. The new technology enables process simulation to be completed within a tiny fraction of a second without losing the high level of prediction accuracy inherent to FEM. The three steps to design an on-line FE model, which are process metamorphosis, mesh design, and process variable design, are described in detail. The procedure is demonstrated step by step through designing actual on-line models for the prediction of the parameters vital for mill set up and control. The validity, as well as the prediction accuracy of the on-line FE models, are examined and discussed
