Scr:Lattice Geometrical Model
A PhD done by one of yade's authors was to develop a Lattice Geometrical Model to simulate fracturing process of concrete and possibly other materials.
you can watch some a video with this model too.
Effect of aggregates – three phases 2D / 3D
Below is the effect of aggregates in 2D and 3D on the stress train curve, using:
- 25% (first column) and 50% (second column) of aggregate area (2D) or volume (3D) in the specimen
- 2D result (first row) and 3D result (second row)
- using the sieve curve shown on the right
Below is a propagation of curved crack in three phase material, 2D in a Nooru-Mohamed experiment. First picture is the experimental result, others are from numerical simulation using Lattice Geometrical Model.
