On the prediction of macroscopic yield surfaces for a pearlitic steel using computational homogenization
Journal article, 2012
In the present work a multiscale modeling framework is used to predict yield surfaces for a pearlitic steel. On the mesoscale a model taking into account the features of the pearlite colonies, i.e. the crystallographic orientations of the ferrite and the cementite lamella orientation, is used. The microscale model includes both the ferrite matrix and the cementite lamellae and the interactions between these phases. The model is used to predict yield surfaces for both isotropic and deformed mesomodels.
