Figures

FIG. 1.

The cross-section of a spherical, coated inclusion composite.

Image of FIG. 2.
FIG. 2.

The two-level recursive scheme. The coated particles are seen themselves as composites. Once homogenized (deepest level), they play the role of homogeneous inclusions for the matrix material (highest level) (Ref. 30).

FIG. 3.

(Color online) The predicted ME voltage coefficients vs the volume fraction of inclusion, fi , and radius ratio, γ, of a BTO/CFO/TD (core/shell/matrix) three-phase composite: (a) ME voltage coefficient and (b) ME voltage coefficient In both (a) and (b), lines are based on the two-level recursive scheme with Mori-Tanaka’s method, while discrete point symbols are based on the finite element analysis.
