Abstract

In this thesis a numerical model is developed to simulate the warm forming of Al¿Mg sheet. An important part of the numericalmodel is the modelling of the material behaviour. Both the hardening behaviour, including temperature and strain rate effects, and the biaxial stress¿strain response of the sheet are considered. Two hardening models are compared: a phenomenological model in which the parameters of a Ludwik¿Nadai hardening model and a power law strain rate relation are made temperature dependent, and a physicallybased model according to Bergström.
