- Assembling different types of materials to ensure long service life in harsh environments such as the marine environment.
- Developing innovative means of assembly that take in-service conditions into account and involve the use of new materials, new alloy grades, new surface treatments, etc.
- Introducing hybrid techniques (bond-welding, etc.) that require extensive studies, to achieve high performance in terms of assembly time or mechanical characteristics.
- Assembly instrumentation
- Characterizing the multi-physical properties of materials and the long-term behavior of bonded and welded assemblies
- Multiscale modeling of physical phenomena during and after assembly, until failure

Development of a multi-material bonded structural assembly providing ballistic protection (2018-2021; in collaboration with the PTR3).
Influence of the manufacturing process on the buckling of a cylindrical shell under axial compression (2017-2020; in collaboration with the PTR5).
Instrumentation and durability of bonded multi-material structures of marine renewable energy production systems (2015-2019).
Behavior, modeling and simulation of the structural bonding of bonded composite structures, under a wide range of temperatures and strain rates, taking aging into account, to improve the durability of marine renewable energy production systems (2014-2019).
13 areas of innovation have been determined for this European project that brings together 37 partners from 11 countries.
The team leads the work carried out on the durability of bonds between a composite module and a metal structure and on the setting up of a high cycle fatigue design calculation chain for steel thrusters made using additive manufacturing, with large-scale validation testing (2017-2020 with PTR 2 and 5).
