RVE Models with Various Filler Morphology for What-if Analysis of Random Heterogeneous Materials

摘要

This paper presents development of representative volume element (RVE)models of random heterogeneous materials with various filler geometries andapplications. The 3D network of filler within RVE is controlled using randomdistribution, probability distribution functions using image analysis, uniform grid andclose packing algorithms. The 3D RVE models generated with filler geometries andviable computational models of various composite systems based on input fillermorphology can be used to predict continuum properties of random heterogeneousmaterials for various applications. Various algorithms used in the RVE modelgeneration rely on filler-to-filler compatibility and contact. The 3D network of fillerswithin RVE models and their seamless integration with analytical tools, 3D solidmodeling and finite element analysis are presented with different filler geometry andmorphology for what-if analysis to quantify continuum properties in differentapplications.
