摘要: In this paper, three-scale stochastic elastic finite element analyses are made for recycled aggregate concrete (RAC) based on nano-indentation digital images. The property of RAC contains uncertainties across scales. It has both theoretical and practical values to model predict its mechanical performance. Based homogenization theory, effective moduli at three different scales obtained using moving window technique, images, Monte-Carlo method. involves the generation a large number random realizations microstructure geometry volume fraction inclusions other parameters. mean value, coefficient variation probability distribution computed considering material multiscale structure. microscopic randomness is taken into account, correlations among five phases investigated. properties used obtain global behavior composite indicated that response variability can be considerably affected by replacement percentage aggregates.
