Mechanics and Engineering Materials

This module introduces a basis grounding on the materials currently used , on their structures and properties as well as the characterization methods. In particular, the approach used will underline the relation between the properties (mechanical and physical) and the structure of the material at a relevant scale (from nano to macroscopic). This knowledge will enable the student to propose well-considered selection of materials in relation to the elaboration and manufacturing processes for a given application. It will also gives to the students the capabilities required for computational mechanics in order to size and design structures according for the different classes of materials and their micro-structure.

I. Mechanical properties and micro-structure

• The main mechanical tests: stress-strain curves
• Interatomic bonds, structure and defects
• Relation between mechanical properties and structure/defects II. Mechanical behaviour and structure sizing
• Linear elasticity and rupture
• Linear viscoelasticity
• Plasticity and work-hardening III. Elaboration, modification of properties of materials (8h)
• Metals and metal alloys
• Polymers and composites
• Physical properties of materials: Electrical and thermal conductivity

Independent work and the acquisition of knowledge and skills will be assessed by means of "micro- tests" (continuous assessment) Final mark = Knowledge mark = 90% exam mark + 10% continuous assessment mark
