Homogeneous solids under complex loading or heterogeneous solids under any type of loading present strain fields of which multi-scales analysis in relation to their microstructure may precisely reveals the deformation mechanism of the material. Our work is focused on the development of an original analysis of the strain and of the deformation mechanism of crystalline and nano filled polymer using Digital Image Correlation techniques. Several sources will be used to image the samples from the white light source to X-Ray allowing for an analysis at the macro/micro scales.
In particular, damage micromechanisms will be studied through X-ray microtomography using the research platform project LEMAX “Ligne d’Etude des Matériaux par Analyse X” at the European Synchrotron Radiation Facility. This latter technique allows a 3D visualization of objects that will be subsequently analyzed by DIC techniques.
