Periodic boundary conditions
Generic 3D periodic boundary conditions are implemented in Yade and handle arbitrary velocity fields. In this example a large plate is introduced, de facto restricting the periodicity to two dimensions. This video is generated with the example script periodicSandPile.py
Modelling progressive failure in rocks
Uniaxial compression test simulation of a synthetic rock like material containing a pre-existing flaw/fracture. Wing cracks initiate at the tip of the disconitnuity and propagate according to the stress field until complete failure of the sample as a result of the coalescence of interparticle microcracks (interparticle bonds breakage).
