In-situ testing under X-ray imaging (ISIS4D)
Platform
ISIS4D platform is dedicated to X-ray microtomography - a non-destructive imaging technique allowing to characterize the internal structure of materials. We have a microtomograph equipped with two X-ray generators as well as several detectors to cover a wide range of resolutions (from 0.4μm to 100μm) and applications (metallic, geological, organic, composite, biological, textile and paleontological materials). In particular, we conduct studies of three-dimensional characterization of the microstructure of materials (dimensional control, characterization of defects) as well as in situ studies under complex loading (coupled multi-physical and multi-axial solicitations). We are open to all academic and industrial collaborations and propose services in line with our expertise.
