Periodic Unit Cell-based Simulation of Materials with Random Microstructure

Result description

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.

    Simulace materiálu s náhodnou mikrostrukturou založená na periodické jednotkové buňce

  • Czech description

    V tomto příspěvku je představena procedura pro generování idelizovaných jednotkových buněk pro aproximaci skutečných mikrostruktur. Geometrie jednotlivých buněk je odvozena z optimalizační procedury formulované pomocí statistických deskriptorů popisujících geometrii náhodného vícefázového média. Aplikace na jednosměrné vláknové kompozity, textilní kompozity a zděné konstrukce dokazují praktickou použitelnost navrženého postupu.
