Préalables
This is an advanced course about the mechanics of materials which is addressed to students having prior knowledge about continuum mechanics, linear theory of thermo-elasticity in three dimensions (tensor representation) as well as some basics of materials science (mechanical properties of amorphous and crystalline materials.)
Thèmes abordés
The course presents different mathematical models used by engineers in order to describe the mechanical reponse of deformable materials as well as their ability to sustain crack extensions. Each model is motivated from the physics and adaptations are suggested in order to account for non-linearity under finite strains, anisotropy of composite materials as well as the influence of temperature, environment and strain rate on the mechanical response. A systematic procedure is presented in order to select materials with optimized mechanical properties.

Contenu
The course will cover the following topics :
· Materials selection procedure to achieve desired mechanical properties (material classes, performance indices)
· Complements of linear thermoelasticity (incl: phase partitioning of strain and stress in composite materials and cellular materials
· Viscoelasticty of polymers
· Plasticity (incl isotropic yield surfaces, elastic springback, residual stresses, cyclic loading)
· Material responses under finite strains (incl hyperelasticity)
· Linear elastic fracture mechanics (toughness, stress intensity factor, crack opening displacement, limits of validity of LEFM, energy release rate)
- Fatigue (total life and crack propagation, materials factor affecting fatigue life)

Méthodes d'enseignement
The course will involve lectures, exercises and as well as PBL (project based learning) in small groups.
Face-to-face teaching will be priviledged but some activities may also be organized in distant mode if required.

Modes d'évaluation
des acquis des étudiants
des acquis des étudiants
During the semester, the students daily work will involve several tests, projects and homeworks graded individually or per group. It will represent 15% of the total grade in June. In case of a resit exam in August, the grading of the semester work will be taken into account only if this raises the final grade.
Both the June and August exams will comprise a written and an oral evaluation. They will correspond to 50% (written) and 35% (oral) of the final grade. As a whole, the exam will aim to assess the level of understanding of theoretical concepts, the learning outcomes of the semester projects, and the problem-solving skills.
The use, for homework and prject reports, of generative AI is forbidden.
