Abstract
In a previous study, a generic micro-macro mechanical model based on the coupling of an incremental mean-field model [1, 4, 5] with the Gurson-Tvergaard (GT) porous plastic law [2, 6] has been developed for the prediction of the mechanical properties of multiphase materials with a large volume fraction of voids. This model has been used in the framework of the FP6 PROHIPP European project to investigate the link between the microstructure and the mechanical properties of spheroidal cast iron. In this contribution, experimental results are presented and an inverse analysis procedure is proposed to adjust the parameters of the model.
