Statistical correlation features are a widely known category of statistical descriptors that may be used to explain the morphology and the microstructure-properties courting. A complete examine has been played for using those correlation capabilities for the reconstruction and homogenization in nano-composite fabrics. Correlation services are measured from diverse concepts akin to microscopy (SEM or TEM), small attitude X-ray scattering (SAXS) and will be generated via Monte Carlo simulations.  during this e-book, diverse experimental concepts resembling SAXS and snapshot processing are offered, that are used to degree two-point correlation functionality correlation for multi-phase polymer composites.

Higher order correlation services needs to be calculated or measured to extend the precision of the statistical continuum process. to accomplish this goal, a brand new approximation method is applied to procure N-point correlation capabilities for multiphase heterogeneous fabrics. The two-point features measured by way of varied recommendations were exploited to reconstruct the microstructure of heterogeneous media.

Statistical continuum idea is used to foretell the powerful thermal conductivity and elastic modulus of polymer composites. N-point likelihood services as statistical descriptors of inclusions were exploited to unravel powerful distinction homogenization for powerful thermal conductivity and elastic modulus homes of heterogeneous fabrics.  Finally, reconstructed microstructure is used to calculate powerful houses and harm modeling of heterogeneous materials.

Garmestani and others [GAR 98, GAR 01, GOK 05, LI 06, LIN 00, SAH 04] have further extended the statistical continuum approach to both composites and polycrystalline materials using two-point functions. Mikdam et al. [MIK 09] have developed an approximation for the three- Approximate Solution for N-Point Correlation Functions for Heterogeneous Materials 45 point correlation functions based on two-point functions. In other research, Mikdam et al. [MIK 09] and Baniassadi et al. [BAN 11b, BAN 11c] have applied the strong-contrast formulation to predict the effective electrical and thermal conductivity of a two-phase composite material where the distribution, shape and orientation of the two phases are taken into account using two-point and three-point correlation functions.
