概要

A constitutive model that describes the macro-stiffness characteristics for fiber reinforced composite materials is introduced. The model utilizes the Eshelby's equivalent inclusion method for describing a particle but with authors'self consistent compliance scheme instead of Mori-Tanaka's meanfield theory, which most other composite models are based on. A separated meso-mechanics analysis verified the accuracy and the reliability of the present model for a fiber dispersed composite over the existing model. A numerical analysis with the developed model revealed that fiber orientation, aspect ratio of fiber, rigidity ratio of fiber/matrix, and volume fraction of fiber are the major controlling factors of the fiber reinforced composite, thus can be regarded to take the role of design parameters of the composite structures.
