濃度の異なる強化基材クラスターを含む複合材料の巨視的特性のマイクロメカニックス解析

Equivalent expression is derived for a mixed double inclusion which is a misoriented inhomogeneous inclusion embedded in an inclusion and it is developed to the composite material containing many clusters consistent of many misoriented inhomogeneous inclusions. Then the macroscopic elastic moduli and stress-fields of such composite materials are analyzed by the resultant equivalent expression. As a result, the magnitude of total internal stress occurring in the composite material is good agreement with that obtained by Taya et.al (JSME A,43-1(2000), pp.46-52.) under high-level clustering condition. Moreover, effects of co-existing various clusters on macroscopic elastic moduli and stress-fields induced in the composite material are examined.
