In-situ testing under X-ray imaging (ISIS4D)

Platform

Description

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.

Expertises

Skills

• Three-dimensional characterisation of the microstructure of a wide range of materials (geomaterials, metal alloys, polymers, composites, etc.).
• Scientific and technical assistance, user support and expertise
(i) as a pre-test for the development of the experiment
(ii) for the choice of acquisition parameters, settings, data reconstruction, etc.
• Processing and analysis of reconstructed data including the use of digital volume correlation with YaDICs open source software developed in-house
• Development of tests for in situ monitoring of the microstructure evolution under coupled multi-physical and multi-axial stresses
(i) Tension-torsion fatigue…
(ii) Chemical damage to concrete
(ii) Couplings between microtomography and other experimental measurements (infrared thermography, image correlation, ...)
