Abstract

Simple analytical results for the size-dependent elastic properties of micro- and nano-sized regular open-celled foams are presented in this paper. The results indicate that at micrometer scale, strain gradient has a dominant effect and at nanometer scale, surface elasticity dominates the effect on the honeycomb elastic properties. In addition, very small micro- or nano- open-celled foams could have a negative Poisson ratio, the elastic properties of nano-sized open-cell foams can be controlled to vary over a range up to around 66% by the application of an electric potential.
