Summary:Modelling material properties for the membrane and interface elements in a finite element model can be problematic, especially considering that the geogrid's pull-out resistance is derived from friction generated on the soil-reinforcement boundary, which in this case is not continuous and has perforations. This is further complicated by the fact that the in-soil stiffness of a geogrid is stiffer compared to the in-air stiffness under which the geogrid is tested.
