## Abstract Poisson's ratio for several lowβdensity plastic foams has been determined in both tension and compression. For polystyrene bead foams and a polyurethane foam, Poisson's ratio is greater in tension than compression. In compression, Poisson's ratio is not linear, showing a larger value be
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
