Anisotropy of foams

Abstract

Cellular materials are often anisotropic, i.e. their properties depend on the direction in which they are measured. In this paper, we model the mechanical behaviour of anisotropic foams to describe the ratio of foam properties in two orthogonal directions in terms of the mean intercept lengths of the cells. Experimental measurements of the mean cell intercept lengths and of the mechanical properties of two polyurethane foams indicate that the model describes anisotropy well.
