Continuum Mechanics

Continuum Mechanics (UE S1-7)

Outline of the course

  1. Continuum limit, conserved quantities and continuity relation
  2. Diffusive processes: macroscopic laws (Fourier's for heat, Fick's law for mass) and microscopic models (random walk, Langevin equation)
  3. Stress tensor and the general equation of motion
  4. Elasticity theory: strain tensor, elastic energy, Hooke's law, isotropic solids, full solution of a few static deformation problems, elastic wave propagation
  5. Fluid kinematics: Lagrangian and Eulerian motion, deformation of fluids, mass conservation
  6. Fluid dynamics: Newtonian viscous stress tensor, Navier-Stokes equation, boundary conditions, Reynolds number, other conservation laws, unidirectional and incompressible flows, perfect fluids, potential flows, vorticity
