A micromechanical study of ductile damage in a finite element framework with advanced meshing capabilities

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 micro-structures are submitted to realistic boundary conditions up to large plastic strains thanks to the combination of Laminography, Digital Volume Correlation and Finite Element Model-ling. The obtained results evidence the effect of the microstructural heterogeneities on the ductile fracture process.
