The formability of aluminum sheet can be improved considerably by increasing the temperature.\ud
At elevated temperatures, the mechanical response of the material becomes strain rate dependent.\ud
To accurately simulate warm forming of aluminum sheet, a material model is required that\ud
incorporates the temperature and strain rate dependency. In this paper, the dislocation based\ud
Alflow hardening model is used. The model incorporates the influence of the temperature and\ud
strain rate effect on the flow stress by means of the storage and dynamic recovery of dislocations.\ud
It also includes the effects of solute level, particle fraction and grain size. Cylindrical cup deep\ud
drawing simulations are presented using shell elements. The anisotropic behavior of the sheet is\ud
described by using the Vegter yield locus. Experimental drawing test data is used to validate the\ud
modeling approach, where the model parameters follow from tensile tests
