多孔材料通常是各向异性的，即它们的特性取决于测量的方向。在本文中，我们对各向异性泡沫的机械行为进行建模，以根据泡孔的平均截距长度来描述两个正交方向上泡沫性能的比率。两种聚氨酯泡沫的平均泡孔截距长度和机械性能的实验测量表明，该模型很好地描述了各向异性。
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.
