Thermal and mechanical properties of materials

The mechanical and thermal properties of materials are at the heart of many applications in the field of materials for energy. After an introduction to these different fields of application, this course aims to define the different concepts necessary to master both the mechanical and thermal properties of materials, limiting itself to bulk materials.

Hourly volumes* :

            CM : 11H

            TD : 9H

The goal is to provide a solid foundation of skills to:

1) understanding of the different phenomena governing the mechanical and thermal properties

2) knowledge of the different classes of materials

3) determination of the elastic constants

4) determination of thermal conductivity

Differential calculus. Matrix algebra. Knowledge in crystallography.

Classical thermodynamics

Final test (1)

1) Thermal properties (5,5 CM - 4,5 TD)

-Microscopic macroscopic link; temperature electrons and phonons; heat capacity (thermal energy storage application)

-Thermal conductivity; heat diffusion law (building insulation application)

-Thermal expansion; microscopic aspect and binding anharmonicity; atypical effects (negative expansion, massive ...) (technological applications)

-Melting and heat resistance (thermal shock)

-Diffusivity in materials

-thermoelasticity

2) Mechanical properties (5,5 CM - 4,5 TD)

- Introduction/definitions: what are mechanical properties?
- Stress/strain relationships:

stresses: normal, tangential
deformations: traction, shear, dilatation
stress-strain curve: elastic domain (Hooke), plastic, striction
definition of the different types of materials
- elastic domain:
definition of the different elastic moduli (Bulk, shear, Young, Poisson)
introduction of elastic constants Cij
elastic energy density
expression of elastic moduli as a function of Cij
application to cubic, quadratic, orthorhombic crystals
