Micro‐CT Finite Element Analysis of Thermal Residual Stresses and Fracture in Metal‐Ceramic Composites

This paper presents a simple way of using X‐ray micro‐computed tomography (micro‐CT) in numerical modeling of material properties of metal‐ceramic composites. It shows step by step the proposed methodology with details of the finite element mesh creation, so that it can easily be reproduced by interested researchers. Two case studies are considered to show the proposed approach at work: i) determination of processing‐induced residual stresses in hot pressed Cr/Al 2 O 3 and NiAl/Al 2 O 3 particulate composites and ii) determination of J‐integral for an interpenetrating phase composite made of porous alumina preform infiltrated with molten copper. The method is straightforward and effective but has its limitations that are pointed out.
