The CEA institute is one of three laboratories operated by the Technological Research Direction in CEA (French Atomic Energy Commission). Its vocation is to help companies to increase their competitiveness by technological innovation and to transfer its technical know-how to industry. Its activities are focused on advanced software, embedded systems, integrated technology, sensor and signal processing. In the NDE field, a department of 100 people is dedicated to Research and Development. The research work involves characterising and sizing defects to evaluate the structural integrity and the lifetime of components, instrumentation developments and modelling.

CEA develops the CIVA software, which is recognised as state of the art simulation software. It is used worldwide by more than 140 companies from different industrial sectors in 34 countries. Dedicated to ultrasonic, electromagnetic and more recently radiographic test techniques, CIVA is the most advanced NDT simulation software and 25 people are directly involved in its development. In the last few years, the CIVA software has become a platform on which several European laboratories have based their modelling developments. CEA conducts many collaborative R&D studies in NDE within a wide range of industrial sectors.

Role in the project

Investigation of the bondline quality using elastic methods based on bulk or guided waves in order to account for different interfacial properties by development of non-linear ultrasonic methods as they reveal structural changes such as thickness variation and interfacial conditions in the adhesive bond. Non-linear effects can be observed for both bulk and guided waves as super-harmonics, sub-harmonics generation and wave-mixing interaction when two waves at two different frequencies are used.    

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 636494.

This project is endorsed by the European Aeronautics Science Network - EASN.
