Description
A hypoplastic constitutive model is used to match the soils behavior realistically.
The model by Von Wolffersdorff (1996) is considered as a reference model for predicting the soil hypoplastic response. This model take into account parameters like critical friction state angle, granular hardness, minimum, maximum and critical void ratio, stiffness ration. The installation process is simulated using coupled Eulerian Langragian CEL approach. The reaction force of the surrounding soil is investigated. Soil nearby displacements as well as effect of the changing stress state and the bulk density is analyzed.
