Abstract:A physically-based material model according to Nes is used to simulate the warm
forming of Al-Mg-Si sheet. This model incorporates the influence of the temperature and strain
rate on the flow stress and on the hardening rate based on storage and dynamic recovery of
dislocations. The effect of size and volume fraction of precipitates are considered by means of
phenomenological and Orowan relations. The anisotropic behavior of the sheet is described by
using the Vegter yield locus. Satisfactory results are obtained for simulation of cylindrical cup
drawing.
