Cracks play an essential role in the degradation of the thermomechanical behavior of ceramic matrix composites. However, characterizing their complex 3D geometries within a complex microstructure is still a challenge. This paper presents a series of procedures, based on X-ray tomographic images, to evaluate the applied 3D strains, including their through-thickness gradients, and to detect and quantify the induced crack networks in ceramic matrix composites. Digital volume correlation and some dedicated image processing algorithms are employed. A novel method is proposed to estimate the opening, orientation and surface area of the detected cracks. The proposed procedures are applied to the images of a SiC/SiC composite tube that has been tested in situ under uniaxial tension with synchrotron X-ray computed tomography.
