Abstract

The multiple scattering of time-harmonic plane elastic waves by random distribution of fibres in concrete was discussed. To account for multiple scattering at high concentration of fibres, a method which combines the generalized self consistent model (GSCM) together with the boundary element method (BEM) and the statistical averaging procedure was used to calculate the frequency dependent properties. The microstructure of the concrete matrix was molded by dispersed aggregate structure to calculate the elastic properties. The results show that the effect of multiple scattering and microstructures can vary phase velocites, attenuations of coherent waves in fiber-reinforced concrete and effective elastic moduli and depend on the frequency.
