Mechanical engineering

Marine, Ingénieure Process & Industrialisation WAAM chez Vallourec

The department trains multi-skilled mechanical engineers capable of leading or participating in projects based on the design, optimisation and realisation of innovative products, facilities and procedures. Training in this area combines mastery of scientific and technological knowledge with learning about state of the art digital simulation tools. The aim is to cultivate the future engineers creativity and encourage them to resolve concrete problems, while taking into account the individual and his/her environment, within a project team.

The program offered combines scientific and technological teaching, with cross-disciplinary and soft skills modules (languages, economics, marketing, general management and project management) and practical experience acquired through projects and work placements (in industry, R&D departments, research laboratories…)

Concerning the scientific and technical aspects of the program, a strong emphasis is placed on understanding physical phenomena, as well as their modelling and numerical simulation.

An area which is also dealt with is the interaction with related sciences, such as mechatronics, materials of the future, acoustics, etc.

Regarding project management, this area is integrated in the projects carried out in both 3^rd and 4^th years. These projects, which are based on both innovation and design, can be carried out individually or within a group.

Students are offered a number of different modules and outlets in order to allow them to construct their own career plan. The final year is mainly devoted to modules within the chosen specialisation or more research-oriented taught modules for those who wish to continue their studies with a PhD. It is also possible to undertake the final year of studies abroad.

The department encourages community and clubs within the school via initiatives such as the « 4L Trophy » (humanitarian rally), the « trophée SIA » (development of innovative vehicles), the realisation of hybrid / electronic vehicles and the development of renewable energy systems.

Classes are taught in French.

Goals to be achieved :
Aptitude à appliquer les connaissances acquises au choix des matériaux en conception mécanique
Course details :
Course content and tutorials:
The course is mainly focused on the designation of materials and in particular metallic materials. An introductory section on the families of materials and their properties is covered. A focus on mechanical properties and mechanical testing is dealt with in more detail.
The second part of the course is devoted to the selection of materials for criterion-based mechanical design. In this context, Ashby's selection method is studied by learning how to calculate performance indices.
This method is applied via a tutorial on Granta Ansys software, which serves as a database of materials and processes.
Practical work content:
During the practical work, reverse engineering is put into practice by studying existing metal parts/products.
Three approaches are used:
- Rewriting the product specifications: the application of the material selection method will enable materials to be classified in such a way as to obtain a list of materials suited to the functions of the specifications.

- Identification of materials in the actual product: the reverse engineering method consists of using the specifications to identify the tests to be carried out in relation to the functions of the part and, ultimately, to identify the material used via the material properties extracted from the tests. This makes it possible to identify the position of the material in the

Prerequisites :
511330|512210|513120|513210|514120|514110
Goals to be achieved :
Identify the mechanisms associated with tribology (dry frictional contacts) for friction, wear and friction-induced phenomena (vibrations, noise, particle emissions, etc.).
Design a braking system combining different multi-physics aspects: tribology; thermomechanics; vibrations.
Course details :
This module is divided into different parts in such a way as to provide a complete overview of the problems associated with the design of a braking system, treated as an example of tribology applied to dry friction.
The concepts of tribology, thermomechanical couplings, materials and friction-induced vibrations are initially dealt with separately.
A common thread is used, dealing with the design of a railway brake system, to apply the concepts covered.
Tests on braking benches are used to understand the definition of representative tests, multi-physics instrumentation and data processing.
Thermomechanical aspects are modelled using the finite element method. The aim is to design a friction braking system with a view to achieving a certain number of performance targets. The modelling of a 'digital contact' is also covered at this stage.
Finally, each year a practical application is proposed, linked to an industrial problem posed by a partner (ALSTOM, HITACHI, etc.).

Goals to be achieved :
Targeted Learning Outcomes
Take into account the issues of work relations, ethics, safety and health at work
Integrate into an organization, lead it and help it evolve: exercise of responsibility, team spirit, commitment and leadership, project management.
Question yourself in order to analyze and evaluate your actions, your managerial practices and actions related to your practice throughout your professional career.
Analyze the management practices of your peers.

Educational innovation
Team management and group interaction will be perfected and put to the test as part of the StratiRac business game. This management simulator is played in teams of 6 or 7 who reproduce a real CODIR, which takes over a company in difficulty.
This serious game therefore reproduces a potentially stressful situation close to the reality of a business: business to turn around, large volume of documents to understand, organization and team strategy to put in place.
The increase in skills is carried out using reverse teaching, but the students are supervised and guided gradually via various educational workshops of 30 minutes maximum.
The seminar is divided into 2 calendar periods, which makes it possible to challenge students in terms of a reflective approach, and to improve their cooperation.
Theoretical and methodological contributions will be made from these analyzes of practices.

The educational objectives are:
- Allow the student to understand complex management and cooperation situations via the context (the CODIR takes over a company in difficulty at the start of the game, short decision-making times, etc.)
- Develop skills specific to teamwork, work on cooperation, organization, delegation of tasks and report on them
- Integrate the social and ethical dimension in the service of strategic performance
- Integrate into this organization: self-knowledge, team spirit
- Know how to evaluate and analyze one's actions, one's managerial practices, in a professional context

Targeted Sustainable Development Goals: SDG 3, 5, 8 and 16
Course details :
Objective: Understand the complexity and dynamics of communication in situations of intercultural interaction and exchange.

Contents:
Introduction to the fundamental concepts underlying the field of
intercultural communication.
Analysis of intercultural communication situations and the cultural components of
