Gustave Zédé joint laboratory

The Gustave Zédé joint research and innovation laboratory was created in late 2015 as a partnership between ENSTA Bretagne and Naval Group. The experimental and modeling research work focuses on issues related to the strength, stability and durability of the materials used, for example, in military shipbuilding. This laboratory provides for the development of innovative ship design tools and numerical fatigue behavior prediction tools for such structures subjected to extreme loading.

The research work conducted at the Gustave Zédé joint laboratory has 3 main areas of focus:

The rapid characterization of the fatigue properties of materials
The rapid characterization of the fatigue properties of assemblies
New manufacturing processes and fatigue behavior

Major projects for 2019

EUROPEAN H2020 PROJECT “RAMSSES”: FOR MORE SUSTAINABLE AND EFFICIENT SHIPS.

This project brings together 37 partners from 11 countries to focus on 13 areas of innovation. 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).

RAPID CHARACTERIZATION PROJECT

Fatigue properties of as-welded and post-weld treated assemblies (2018-2020, CIFRE PhD thesis).

PROJECT “EA AMERICO”

Improving design methods for the production and industrialization of submarine hulls. The project will focus on two major topics: forming and fatigue behavior. The goal is to better define the initial mechanical state of the formed structure so as to take better account of its impact on the structure’s in-service behavior. (2019-2022)

Projet EA INCOLA (2020-2022).

Il porte sur la fatigue multiaxiale des arbres d’hélice.

Dans le cadre d’une thèse, les travaux visent la caractérisation rapide des propriétés en fatigue des matériaux métalliques utilisés.
