強化基材クラスターを含む複合材料のFEM解析

抄録

Composite materials containing many clusters of reinforcements are analyzed by using the double inclusion method presented by one of the authors and the solutions of stress and strain are expressed explicitly in the previous report. Stresses occurred in such a composite calculated from the solution are good agreement with the results obtained by Taya et.al (JSME A,43-1(2000), pp.46-52.) in the case of the condense cluster in which the volume fraction of reinforcements is larger than that in its surroundings. However, no results have been reported in the case of the dilute cluster with smaller reinforcements so far. Therefore, FEM analysis may be performed to the dilute cluster problem. In the present report, the procedure of elements subdivision for FEM analysis is examined by taking the Dirichlet tessellation for the dispersed reinforcements into consideration.
