Mechanical Engineering for Materials and Manufacturing Processes

Head of Specialisation: Erwan VERRON

Objectives

The objective of this specialisation is to train engineers capable of getting to grips with complex design or manufacturing problems in their entirety. Two examples are provided to demonstrate the general principle:

  • Parts design requiring the following phases: choice of appropriate materials, modelling of mechanical behaviour, simulation based on a rigorously-defined question (boundary conditions) using appropriate and effective tools, and finally dimensioning which may call on damage, fatigue or fracture criteria adapted to the type of material and mechanical loading.
  • Parts manufacture using an appropriate process, taking account of the multi-physical aspect of the process/material combination and finally modelling and numerical simulation of the problem, in order to obtain optimal conditions for processing (pressure, temperature, time).
Innovation is the key issue at stake: the need to develop and produce new products combining materials and processes that can be industrialised profitably on a large-scale whilst respecting the environment. In this context, training in mechanical engineering for manufacturing, with expertise in production and implementation processes, is indispensable. Very few general engineering schools propose this type of course today.  Innovation is at the heart of this specialisation, which offers a broad range of courses. Students will study the different structural materials: metals, polymers and composites. The course also covers the different scientific tools for the mechanics of materials: experimental tools (mechanical tests, X-ray microtomography, image correlation, theoretical tools (multi-physical modelling of processes) and numerical tools (finite element simulation).

The teaching staff are internationally recognized for their research work and for their close relationships with industry: EADS-ESI Chair Professor Francisco Chinesta, Faurecia Chair Professor Christophe Binetruy, partnerships with Areva, Michelin, Safran, Renault, BMW, General Electric etc.

NB Successful completion of a university course in Continuum Mechanics is a pre-requisite for this specialisation.

Sectors of activity and employment prospects

A broad range of careers are accessible to students following this specialisation: engineering consulting, R&D (especially post PhD qualification), test and process engineers, methods engineer, progressing particularly towards expert positions, but also management posts. The knowledge and skills acquired open up opportunities across all the main industrial sectors - aeronautics, automotive, naval and energy.
