Description

This 42-hour course introduces the basics of continuum mechanics: we study motions, deformations and stress fields in media that we consider from a macroscopic point of view, as opposed to a corpuscular description. More precisely, we analyze these physical phenomena by describing them mathematically.

Syllabus

The course is classically divided into three parts:

  • Kinematics of Continuous Media
    Conservation law. Stress tensor.
    Stress tensor study
  • Linear elasticity equations
    Classification and variational formulations of elasticity problems
  • Notions of incompressible fluid mechanics: fluid kinematics, acceleration, vorticity, incompressibility and conservation of volume. Fluid dynamics: Behavior laws, viscosity, Newtonian fluids, Navier Stokes equations, scaling and symmetries. Some analytical solutions: Couette, Poiseuille. Stokes equations and weak formulation with various boundary conditions. Existence, uniqueness and regularity by Lax Milgram Babuska theorem. Use of finite element codes for simple flows.
