An equation is presented for the prediction of the Poisson's ratio of porous materials. The equation is strictly derived for spherical porosity and isotropic materials and it is valid for the whole porosity range. For low porosity, the equation coincides with a published equation, which has been ver

Poisson's ratio, n, is a fundamental parameter characterizing the mechanical behavior of a material. Because the ratio of the bulk to the shear modulus, B/G, becomes infinite when n ¼ 1=2, it is often assumed that the bulk modulus becomes very large as a material approaches ''incompressibility.'' Th
Negative Poisson's ratio (NPR) foams have been predicted to have unusual acoustic properties. To measure these, polyurethane foam was chosen to serve as a model system. Negative Poisson ratios were produced in open cell, reticulated polyurethane foams by heat setting the foam which had been three-di
