OS0119 Analysis on Influence of Variation in Volume Fraction of Fiber on Stochastic Property of Homogenized Elastic Property of Fiber Reinforced Composite Material

Abstract

This paper discusses influence of variation in volume fraction of fiber on a stochastic property of a homogenized elastic property of a fiber reinforced composite material caused by a random variation in a material property or geometty of component materials. The influence is analyzed with the perturbation-based analysis using the equivalent inclusion method. With numerical results, influence of volume fraction variation on the stochastic property is discussed. Also, a limit of random variation of volume fraction of fiber in order to control a random variation of a homogenized elastic property of a composite to be less than random variation of elastic properties of component materials is investigated.
