ABSTRACT
In this paper a procedure is introduced for the generation of idealized periodic unit cells approximating real complex microstructures. In particular, geometry of such a unit cell is derived from an optimization procedure formulated in terms of statistical descriptors characterizing a microstructure of random multiphase media. Applications to fiber-reinforced composites, woven composites and masonry structures are examined to illustrate the applicability of the presented methodology.
