Abstract
The use of cast aluminum alloys for automotive components has greatly increased in the past two decades due mainly to the lower density and increased thermal conductivity of aluminum alloys as compared with cast iron. A unified constitutive model is developed for the aluminum alloy A1319 under T7B thermal treatment. The model is based on two state variables: the drag stress and the back stress. The constants for the model were determined systematically from isothermal experiments and the capabilities of the constitutive model were checked by comparing the simulations with isothermal and thermo-mechanical experiments. The results show that the model provides successful simulations for the material response over a broad range of temperatures and strain rates, including cyclic softening and thermal recovery.
