000014232 520__ $$2eng$$aMetal-ceramic composites with lamellar microstructure are a novel class of composites produced by infiltration of freeze-cast or icetemplated ceramic preforms with molten aluminium alloy. Due to the cost-effectiveness of production and relatively high ceramic content they are attractive for automotive, aerospace and biomedical engineering applications. A hierarchical lamellar microstructure, with randomly orientated domains in which all ceramic and metallic lamellae are parallel to each other, is the result of the ice crystal formation during freeze casting or ice-templating of preforms from water-ceramic suspensions. In this paper, a single-domain sample of metal-ceramic composite with lamellar microstructure is modelled theoretically using a combination of analytical and computational means. Stress field in the ceramic layer containing multiple transverse cracks is determined using a modified 2-D shear lag approach and a finite element method. Degradation of stiffness properties of the sample due to multiple transverse cracking is predicted using the equivalent constraint model.
