THE EFFECTIVE POISSON RATIO OF TWO-PHASE COMPOSITES
Original language description
The Voigt-Reuss and Hashin-Shtrikman bounds for the bulk and shear modulus impose certain restrictions on the effective Poisson ratio of two-phase composites beyond the general requirement to lie in the range between ? 1 and + 0.5. It is found that a composite of non-auxetic phases may be auxetic, when both phase modulus contrasts (bulk modulus ratios and shear modulus ratios) are sufficiently different from unity. In particular, it is shown that even composites with two phases of the same (positive) Poisson ratio can have a negative overall Poisson ratio. When one of the phase modulus contrasts is close to unity, auxetic behavior cannot be achieved, and when both phase moduli contrasts are small the effective Poisson ratio is well predicted by the mixture rule (e.g. in ceramic composites).
