Full 3D damage characterisation of SiC/SiC composite tubes by X-ray tomography
Résumé
Matrix cracking in SiC/SiC composite tubes is characterised from in situ tensile tests performed under x-ray synchrotron tomography. Digital volume correlation is used to estimate semi-local strains and to detect and extract cracks from the 3D images. Two populations of cracks can be distinguished. Their spatial distribution within the tube thickness is studied and their evolution is quantitatively analysed, such as subvoxel opening.
