The Mechanics of Materials unit is composed of 36 hours of courses, 3 hours of practical work and 3 hours for exams and involves 3 teachers: J. Bruchon, C. Desrayaud and H. Klöcker. Students will reinforce and develop their general knowledge from the 1st year course on Continuum Mechanics and will acquire the necessary notions for the understanding of the mechanical behaviour of materials, of essential importance to the engineer. In addition, with this unit being the introductory unit to the Mechanical Engineering major, knowledge acquired will serve as a foundation for the other units of the major course.
After a first three hours introduction course (general presentation and practical course in the mechanical testing room), the 36 teaching hours of the Mechanics of Materials unit will be organised as follows :
The first course will establish the links with the notions of continuum mechanics studied in the 1st year and introduce the concepts (notions of configuration, objectivity) and the tools (measuring constraints and deformations) necessary to deal with major deformations. The second course will go further into the notion of the mechanical behaviour of materials. Only linear elastic behaviour was studied in the 1st year. Here the notions of plasticity and work or strain hardening are introduced, allowing the behavioural description of a large variety of materials. Finally the third course will use these notions in the formal context of continuum thermodynamics, automatically leading on to the different forms of thermodynamically admissible couplings between the different mechanical and physical values introduced.
These courses will be completed by a 3 hour exam (2 X 1.5h).

Formalism of continuum mechanics in major deformations (10,5h) Establish the links with the notions of continuum mechanics studied in the 1st year and introduce the concepts (notions of configuration, objectivity) and the tools (measuring constraints and deformations) necessary to deal with major deformations. |
| Course | Mechanical behaviour of materials (15h)) Further details of the mechanical behaviour of materials. Only linear elastic behaviour was studied in the 1st year. Here the notions of plasticity and work or strain hardening are introduced allowing the behavioural description of a large variety of materials. |
| Course | Continuum thermodynamics (10,5h) Introduction to the formal framework of continuum thermodynamics, for the derivation of behavioural laws, automatically leading on to the different forms of thermodynamically admissible couplings between the different mechanical and physical values introduced. |
