Application of the Lamel model for simulating cold rolling texture in molybdenum sheet

Liu, Y.S Delannay, Laurent [UCL] Van Houtte, Paul [UCL]

The cold rolling texture in a molybdenum sheet was simulated using different plasticity models. The Lamel model made a prediction closer to the experimentally determined texture than the “full constraints” (FC) Taylor model and the “relaxed constraints” (RC) Pancake model. However, the Lamel model did not perform as well as in previously investigated low-carbon steels. Having observed that the experimental fibre-profiles appear intermediary between the predictions of the Lamel and the Pancake model, two revised compromise models are developed, by which the simulated results can be further improved. The applicability of the various models is physically motivated.
