Dissemination of IT for the Promotion of Materials Science (DoITPoMS)



After working through this teaching and learning package, you should:

  • Understand the concept of dilatation
  • Have a feeling for 'typical' angles of repose for granular materials
  • Recognise how friction, cohesive forces and the shapes of grains all affect the angle of repose of a pile of granular material
  • Be able to appreciate the various ways in which soil can fail in compression and how the choice of failure mode is a function of the water content of the soil
  • Be able to recognise the factors which cause soil to fail catastrophically and flow like a liquid – the phenomenon of liquefaction
  • Recognise that quicksand is dangerous, but that if you ever happen to fall into quicksand, you can reassure yourself that you will not be sucked beneath the surface.
