The research work developed in this area, by its nature, involves more multidisciplinary interaction than that of the other hubs and combines theoretical, digital and experimental studies on the behaviour of materials and structures in interaction with their environment and/or their manufacturing process. This work relates brings coupled physical phenomena into play, such as ships subject to slamming in maritime environments, the thin hot shaped sheet metal structure then impacted up to breaking, the laser welding process involving transfers of energy and mass. These couplings are the key concept which brings the researchers together in this hub.
