“…They are almost identical at frequencies where k 1 a < 1 and are also very close to each other at high frequencies. This is quite contrary to the expectation [Kanaun et al 2004] that these two models would predict substantially different results in the wave speed and coherent attenuation since the matrix phase is treated quite differently in these two models, as a continuous phase in the EMT-2 as opposed to an equivalent inclusion in the EMT-1. Relatively large deviations are seen at the frequencies where the attenuation has a peak due to the rigid-body resonance of the inclusions (see Figures 2 and 3) and at some high frequencies where numerous elastic resonances occur (see Figure 4).…”

“…As shown in [Kim et al 1995], this theory was very successful in predicting the effective wave speed and attenuation in random particulate composites for wide ranges of frequency and volume fraction. A second variant is the dynamic extension [Sabina and Willis 1988;Bussink et al 1995;Kanaun and Levin 2003;Kanaun et al 2004] of the static self-consistent theories of [Budiansky 1965;Hill 1965]. The major difference between these two theories lies in how the roles of constituents are treated, which will be discussed later in this paper.…”

“…Accepted pattern consists of O node and E ± ij points, separated from the point O by distance λ ij τ . In the future discussion values of the functions at the point O are denoted by upper index "0", values at the points E ± ij are denoted by lower index "ij" and the upper index "±" (for example σ ± ij ), and values at point A are not not denoted by an additional index [13][14][15][16].…”

“…One of the two basic patterns in self-consistent approach is effective medium. The fundamental hypothesis in the group of the effective medium methods explains that the composite material outside the abutting of the inclusion may be varied by the effective properties of the entire composite that is assumed a homogenous medium (Kanaun 2004). The next self-consistent method is the effective field method.…”

“…By using both the effective medium and effective field methods, Kanaun et al (2004) extracted the equations of elastic wave scattering in composites containing of spherical inclusions. They showed that the effective field method has some advantages than the effective medium.…”
