3D modeling and experimental investigation on the damage behavior of an interpenetrating metal ceramic composite (IMCC) under compression

In this study, an interpenetrating metal–ceramic composite, manufactured via gas pressure infiltration of AlSi10Mg into open porous alumina foam is investigated three dimensionally on its damage behavior under compression. Experimentally, compression tests as well in-situ computed X-ray tomography experiments with digital volume correlation evaluation were carried out. Numerically, the reconstructed microstructure composite was modeled and simulated FEM simulation, to investigate microstructural onset failure behavior. Three stages could be observed, which are described in detail macroscopic level. Additionally, a comparison between simulation experiment made, correlations elaborated observed differences discussed.
