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