A study of the effect of microstructural heterogeneities on ductile damage.
Résumé
Accurate prediction of ductile fracture of metallic materials requires sufficient understanding of the underlying micromechanical phenomena, especially if complex multiaxial and non-proportional loadings are to be considered. In this micromechanical study, real microstructures are submitted to realistic boundary conditions up to large plastic strains thanks to the combination of Laminography, Digital Volume Correlation and Finite Element Modelling. The obtained results evidence the effect of the microstructural heterogeneities on the ductile fracture process.
