From Yade

Yade includes tools to simulate triaxial tests on particles assemblies. This pre-processor (and variants like e.g. CapillaryTriaxialTest) illustrate how to use them. It generates a scene which will - by default - go through the following steps :

  • generate random loose packings in a parallelepiped.
  • compress the packing isotropicaly, either squeezing the packing between moving rigid boxes or expanding the particles while boxes are fixed (depending on flag internalCompaction). The confining pressure in this stage is defined via sigmaIsoCompaction.
  • when the packing is dense and stable, simulate a loading path and get the mechanical response as a result.
