Analysis of interpenetrating metal ceramic composite structures using an enhanced random sequential absorption microstructure generation algorithm

Abstract In this paper, we present the analysis of an interpenetrating metal ceramic composite structure. We introduce a new generation algorithm for modeling microstructures with connected, spherical cavities embedded into open-porous foam The method uses geometric ansatz and is designed to create structures special topology, as investigated consisting connected AlSi10Mg phase showing shapes Al 2 O 3 preform. Based on introduced enhanced random sequential absorption approach, generated yield numerical insights material that are not accessible by experimental techniques. compared reconstructed from CT scan data considering microstructural features mechanical behavior. show proposed able generate statistically equivalent using only small number statistical descriptors. formulation validated compression tests including plastic yielding in aluminum damage progression phase. Both pure preform considered analysis, good agreement found between microstructures. Furthermore, observations reveal importance local geometrical sphere arrangement respect A validation results presented it shown model predicts properties gives meaningful structural interplay. Finally, discuss potential investigation failure mechanisms.
