Element Method allows a detailed view into the interaction of the particles with the geogrid. Figure 1 shows a sketch, which demonstrates the mechanism of interlocking.
2 GEOGRID MODEL
2.1 Geogrid model set-up
The numerical modeling was performed using the Particle Flow Code (PFC). This code is based on the DEM using stiff spherical particles with deformable contacts and breakable bonds in between (Itasca 2003, Konietzky 2003).
