Hi everyone, i am new ! i need to model a pullout test of a geogrid embedded in a sandy soil. i am worried about the interaction to set.
i red in literature to give two times contact pair to simulate the interaction between ggr-soil (ggr face down-up face of soil under and ggr face up- down face soil above) using a penalty interactoin (μ=0.4). how can i set the soil-to-soil contact ? i could use constraint, tie but am am not complety sure on the way i am walking... i use 3D stress element for the soil and membrane elements for the ggr both with linear elastic behaviour.
Thank for your help !![[bowright]](/data/assets/smilies/bowright.gif "[bowright] [bowright]")
