Summary

The newer low density cellular materials such as aluminum foams are being produced at a low cost by several companies thanks to recent developments in manufacturing methods. They show potential for use in light-weight structures. One of their interesting properties is the amount of energy absorbed during the deformation which is directly related to the way the material collapses in compression. We will focus our study on the compression behavior of these aluminum foams. We performed 3D inspections by means of X-ray computed microtomography (XRCMT) on a commercial foam at different deformation stages in compression. XRCMT has recently emerged as a powerful technique capable to give a non destructive picture of the interior of the structural materials including foams. We also present a method to transform the images of the actual microstructure into a mesh which can be used to model the behavior by finite element calculations. We finally use these calculations to assess the stress distribution inside the compressed walls.
