Abstract

The formability of Al–Mg sheet can be improved considerably, by increasing the temperature. At elevated temperatures, the mechanical response of the material becomes strain rate dependent. To accurately simulate warm forming of aluminium sheet, a material model is required that incorporates the temperature and strain-rate dependency. In this paper hardening is described succesfully with a physically based material model for temperatures up to 200 ◦C. At higher temperatures and very low strain rates, the flow curve deviates significantly from the model. Strain rate jumps still pose a serious problem to the models
