Digital Image-based Analysis of Morphology for Porous Media

To understand the correlation between the microstructure and macroscopic poperties and behaviors for porous media, a novel digital image-based analysis technique is presented. It consists of digital image-based modeling, morphology analysis, and multi-scale stress analysis. This paper focuses on the morphology analysis that studies statistically the heterogeneity and variety in pore sizes, shape and dispersion. The analysis of dispersion of a vast number of pores has led to the quick prediction of stress concentration, which is of help to the multi-scale stress analysis. An application to porous alumina with spherical pores is shown.
