That´s the problem - I checked all geomechanical materials. The problem is the non linear material behaviour. soil has almost no linear range and also reacts different on un- and reloading. I thought about the use of hardening models with only a very small range of linear elasticity. But the next problem is that additionally the soil stiffness depends on the S3 stress state. This means withi increasing depth you have different stress strain relations, means a different curve...
