Two-scale study of the fracture of an aluminum foam by X-ray tomography and finite element modeling
Résumé
Iron-rich inclusions were identified in an aluminum foam in high-resolution images obtained with local tomography. • A tensile test followed by X-ray tomography showed that struts fracture mainly occurred in inclusions-rich regions. • The finite element model taking into account the inclusions was based on image processing of the highresolution images. • The model with the inclusions resulted in local stress concentrations explaining the early fracture of some struts.
