In situ experiments in X ray tomography:
Exploring the interior of ordinary materials to improve their mechanical analysis

 Maire

Abstract

X ray computed tomography is a 3D non-destructive technique to observe the interior of materials. Coupled with in situ experiments, it has been used by our group since 1998 to initially study damage of metals and deformation of cellular materials. Since these early studies, the method has improved drastically in terms of spatial and temporal resolution. Digital Volume Correlation can be used to measure the local strain during the tests and all this can be analyzed by Finite Element modelling directly based on the tomograms.
This lecture will present some recent experiments where we have used this combination of methods to understand the mechanics of ordinary materials and/or systems ("ordinary" means here "widely used in everyday life").
To conclude, the activities of MatéIS in the field of powder metallurgy and additive manufacturing will also be presented and used to exemplify further the usefulness of the technique.


Biography

Eric Maire is CNRS research director (DR1) at the MateIS lab, INSA de LYON Villeurbanne, France. He is director of the lab (hosting 170 staff members) since January 2019. He completed materials engineering studies, in 1995 at INSA Lyon. He then was a post-doctoral fellow at McMaster University (Ontario, Canada) before being hired by the French CNRS in MatéIS in 1997.
He pioneered in situ experiments in X ray Computed Tomography, originally at synchrotrons and more recently on laboratory tomographs. More generally, he focusses his research on materials science, trying to understand the relationship between microstructure and properties. He studies deformation and damage in metals and composites and in highly porous cellular materials.
He also studies materials processing and developed a recent interest in materials for energy storage (lithium Ion batteries). He supervised about 20 doctoral theses and 10 post-docs. He spent a one-year sabbatical in Harvard University in 2010 and was invited professor for one month in the Tohoku University in 2015.
He has authored and co-authored more than 250 articles in international journals and received over 11000 citations (google scholar).
