This paper proposes a digital image-based analysis of porous ceramics to study numerically the correlation between the heterogeneous microstructure and the macroscopic properties and behaviors. The homogenization method is the core technique of the multi-scale stress analysis with the help of the finite element method. The microstructure modeling is carried out practically by the digital image-based technique and the high resolution X-ray CT machine. The morphology analysis is very useful for the understanding of the heterogeneity and the microstructure modeling. The quantitative evaluation of the calculated microscopic stress distribution is very important, and therefore a practical post-processing tool "V-SEM" has been developed.
