  • Elasticity (recommended)

What it covers

Topics

  • Tensor algebra and calculus
  • Kinematics of deformation: deformation gradient, Green and Almansi strain, polar decomposition
  • Stress measures: Cauchy and the Piola–Kirchhoff pair
  • Conservation of mass, momentum and energy
  • Constitutive theory: objectivity and isotropy
  • Elastic and hyperelastic materials, viscous fluids, viscoelasticity
  • Thermodynamic restrictions and the Clausius–Duhem inequality

Results worth carrying out

  • Deformation gradient

    F=∂x∂X\mathbf{F} = \frac{\partial \mathbf{x}}{\partial \mathbf{X}}
  • Green–Lagrange strain

    E=12(FTF−I)\mathbf{E} = \tfrac{1}{2}\left(\mathbf{F}^{\mathsf{T}}\mathbf{F} - \mathbf{I}\right)
  • Balance of linear momentum

    ∇⋅σ+ρb=ρa\nabla\cdot\boldsymbol{\sigma} + \rho\mathbf{b} = \rho\mathbf{a}
  • Clausius–Duhem inequality

    ρ(ψ˙+ηθ˙)−σ ⁣: ⁣D+q⋅∇θθ≤0\rho\left(\dot{\psi} + \eta\dot{\theta}\right) - \boldsymbol{\sigma}\!:\!\mathbf{D} + \frac{\mathbf{q}\cdot\nabla\theta}{\theta} \le 0

This map tells you what a course contains. The summaries, the tutoring and the people who already took it are the part you get by joining.

The topic outlines are not official syllabi. The university publishes a catalogue blurb per course, not lecture-by-lecture material, so each outline describes what a course of that name, at those hours, with those prerequisites teaches at engineering schools generally, cross-checked against the standard textbook for the subject. Treat it as an informed map, not as a transcript of the lectures.
