• On Evaluation of the Mechanical Property of Composite Material by the Homogenization Method

抄録

A numerical scheme to evaluate the elastic stiffness and strength of heterogeneous material, which have been proposed by authors based on the theory of homogenization, is applied to fiber reinforced composites, and its validity for evaluating their mechanical properties is examined. Results show that the numerical scheme can give fairly good predictions as for the elastic stiffness, but it can only predicts value of strength near to the experimental data since the numerical scheme does not take the existence of initial defects in the composites into account. However, it can conclude that our proposed method can use for evaluation of mechanical property of composite material at some first stage of design since the method needs only the mechanical properties of each materials of which the composite consists and a graphical data representingthe geometric feature of the composite structure.
