Opens up

Nothing in this catalogue lists it as a prerequisite.

What it covers

Topics

  • Plasticity fundamentals: yield criteria, flow rules, strain hardening, effective stress and strain
  • Bulk forming: forging, rolling, extrusion, wire drawing
  • Force analysis by slab, upper-bound and slip-line methods
  • Sheet forming: deep drawing, bending, stretching
  • Forming limit diagrams and formability
  • Friction and lubrication in forming
  • Hot against cold work, defects and tooling

Results worth carrying out

  • Flow curve

    σˉ=Kεˉn\bar{\sigma} = K\,\bar{\varepsilon}^{\,n}
  • von Mises effective stress

    σˉ=12(σ1σ2)2+(σ2σ3)2+(σ3σ1)2\bar{\sigma} = \frac{1}{\sqrt{2}}\sqrt{(\sigma_1-\sigma_2)^2 + (\sigma_2-\sigma_3)^2 + (\sigma_3-\sigma_1)^2}
  • Rolling force, slab analysis

    FYˉwRΔhF \approx \bar{Y}\,w\,\sqrt{R\,\Delta h}

Figures worth knowing

  • Forming limit diagram
  • Slip-line fields
  • True stress-strain curves
  • Process schematics

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.
