Key characteristics
The CRED is a dynamic and static test platform which can produce material stress up to the high deformation rates that occur during structural and impact crashes, or during high-speed shaping and assembly processes. Quasi-static stress and fatigue can also be tested on the CRED platform. Our partners are in the aerospace industry, e.g. Airbus and Safran, in energy, e.g. Areva, the automotive sector e.g. Faurecia, PSA, Renault, Vibracoustic and the naval sector e.g. Naval Group.
The Crossbow system allow a tensile and compressive dynamic characterization of materials. This test facilities is hosted at the GEM laboratory
