Modification of a thermomechanical model to predict constitutive behavior of Al-Mg-Si alloys

A previously developed constitutive model for quantification of the effect of the condition of Mg and Si in AA6xxx alloys was used for the prediction of the flow stresses measured by plane strain compression (PSC) tests. As an extension of earlier work, two AA6xxx alloys were subjected to different thermal pretreatments and were plane strain...
