New explicit formulas for the effective piezoelectric coefficients of binary 0-3 composites
The explicit formula for the effective dielectric constant of binary 0-3 composites (Poon and Shin, J. Mat. Sc. 39 (2004) 1277–1281) is extended into two explicit formulas for the prediction of the elastic proper...

Dependence of polarization offset on driving frequency, film thickness and composition gradient in compositionally graded ferroelectric materials
We studied theoretically the effects of frequency and film thickness on the charge offset of the compositionally graded ferroelectric films. The time-dependent space-charge-limited conductivity has been used t...

A simple explicit formula for the effective dielectric constant of binary 0-3 composites
We have derived a simple, analytic formula for the prediction of the effective dielectric constant of binary 0-3 composite materials. In comparison with a popular formula in the field (Jayasundere and Smith [1...

Effective conductivity of a composite of poly-dispered spherical particles in a linear continuum
Rayleigh's method is used to find the electric potentials of a composite of poly-dispered spherical particles in a linear continuum in an external electric field. Based on the solutions of potentials, analytic...

Statistical spherical cell model for the elastic properties of particulate-filled composite materials
The single spherical cell model of F. J. Guild et al. (J. Mater. Sci. Lett. 13 (1994) 10) is extended to take into account the statistical spatial distribution of the inclusions in particulate-filled composite ma...

A dielectric binary mixture formula with an interaction term
A new dielectric binary mixture formula that generalizes Beer's equation is derived by imposing an effective medium theory on the simple rule of mixtures modified by the addition of an interaction term. Dielec...
