本文导出了由含有高浓度刚性球形夹杂物悬浮液的连续基体相组成的复合材料的有效弹性性质的新结果。该复合材料的类型，承认的限制情况下，完全包装的包含相对应的多分散悬浮液。从几个不同的理论微观力学模型得到的分析形式被发现有很大的不同，这提供了一个高度区分的手段，比较它们的物理意义。各种模型也进行了评估与关键的实验数据。对纤维复合材料的计算结果进行了推广。
New resultsare derived for the effective elastic properties of composite materials composed of a continuous matrix phase containing a highly concentrated suspension of rigid spherical inclusions. The composite is of the type that admits the limiting case of full packing of the inclusion phase corresponding to a polydisperse suspension. The resulting analytical forms from several different theoretical micro-mechanics models are found to vary widely and this provides a highly discriminating means of comparing them with respect to their physical significance. The various models also are evaluated with critical experimental data. Some extensions of the results are provided for fiber composite materials.
