X Ray Tomography Study of Cellular Materials: Experiments and Modelling

This paper summarizes different results obtained by the authors applying X-ray tomography to the study of cellular materials (metals, ceramics and polymers). From the 3D images, three different kinds of analysis are carried out. The first is image processing to retrieve the morphological characteristics (density, size, tortuosity) of the studied materials. The second is the analysis of the deformation modes using in situ or ex situ mechanical tests (tension, compression, fatigue). The third is devoted to FE calculations in which models are produced to represent as exactly as possible the architecture of these materials as seen in tomography. These different points are successively presented and exemplified in the present paper.
