Various models are proposed to composite materials including clusters of reinforcements. In such models, the concentration of reinforcements in the cluster is generally very high compared to that of the outside region of the cluster. However, in realistic composite materials, the difference of concentrations inside and outside of the cluster is relatively small. In the present study, the so-called low-level cluster model constituted by misoriented reinforcements is analyzed by the modified mixed double inclusion method proposed by authors and stresses and strains induced inside and outside of the cluster are expressed explicitly. The total internal stresses obtained are good agreement with results obtained by Taya et.al (JSME A,43-1(2000), pp.46-52.) in the high-level clustering region.
