Computational Studies on the Effective Properties of Two-Phase Heterogeneous Media
… Carlo scheme. The continuum contains circular, spherical or ellipsoidal inclusions that are either uniformly or randomly embedded in the matrix. The computed results are compared to the applicable effective medium theories. It is found that the random distribution, permeability and particle …

Assessment of dielectric models and their application to polymer matrix composites
… reduced by mixing the matrix with hollow ceramic spherical inclusions. To predict the effective dielectric constant of the composite, effective medium theory based on Clausius-Mossoti equation was used. It was found that predictions for effective permittivity, based on this relation, correlate …

ΣΚΕΔΑΣΗ ΘΕΡΜΟΕΛΑΣΤΙΚΩΝ ΚΥΜΑΤΩΝ ΣΕ ΣΥΝΘΕΤΑ ΥΛΙΚΑ ΚΑΙ ΠΡΟΣΔΙΟΡΙΣΜΟΣ ΤΩΝ ΘΕΡΜΟΜΗΧΑΝΙΚΩΝ ΤΟΥΣ ΙΔΙΟΤΗΤΩΝ
… OF THESE INTEGRAL REPRESENTATIONS, NORMALIZED SPHERICAL SCATTERING AMPLITUDES ARE INTRODUCED FOR THE DISPLACEMENT AS WELL AS THE TEMPERATURE FIELD. THE THERMOELASTIC SCATTERING CROSS SECTIONS ARE ALSO INTRODUCED. USINGTHE LOW-FREQUENCY EXPANSION, THE SCATTERING PROBLEM IS REDUCED TO A SEQUENCE …

Deoxidation mechanisms in liquid steel.
… with a decrease in the size and number of inclusions observed. This continued to a plateau level of total oxygen concentration and mean inclusion diameter.Samples removed from the melts prior to deoxidation were found to contain globular MnO-FeO inclusions. It was discovered that the …

Microplastic deformation of polycrystalline silver chloride containing a small volume fraction of hard inclusions
… strains are generated between the AgC1 and spherical inclusions by quenching. The critical sphere diameter dp required for punching compares favorably with the predictions of Ashby and Johnson (1969). For spheres larger than the critical diameter, the data are well-fit by a stochastic model …

Prediction of in-situ asphalt mixture density using ground penetrating radar: theoretical development and field verification
… better. To account for the effect of the non-spherical inclusions in asphalt mixture and further improve the density prediction accuracy, a shape factor was introduced into the modified Bottcher model. Nonlinear least square curve fitting of the field core data indicated that a shape factor of …

Characteristics and modeling of the fracture properties of polymer-silica microparticulate composites via macroscopic scratch tests
… Although it is well known that the addition of inclusions can lead to improved multi-phase material properties, the characterization and prediction of these material properties is of current research interest. In this thesis, we evaluate the effect of spherical inclusion content on the material …
