In-situ observation of tensile deformation of open-cell nickel foams by means of X-ray microtomography

Résumé

The aim of this paper is to describe the initial cell morphology of an open-cell nickel foam and to follow its evolution during tension. For that purpose, in situ X ray microtomography tensile tests have been performed at E.S.R.F. with a resolution of 10um. The first step of the 3D quantitative image analysis of the 3D reconstruction images is to close the cells in order to identify them individually. The 3D segmentation methodology is explained in detail. The, the main parameters such as cell size distribution and the cell orientation are determined at each stage of deformation and linked to the macroscopy mechanical behaviour of nickel foams
