In the Geotechnical Analysis add-on, the high-quality material model "Modified Hardening Soil Model" is available. This material model is suitable for a variety of soils and is able to appropriately represent the following properties of the real soil.
- Stress dependence of soil stiffness
- Load path dependence of soil stiffness
- Plastic strains even before reaching the limit condition
- Increasing shear resistance with increasing mesh refinement
- Increasing yield strength with increasing stress until reaching the limit yield condition
- Failure criterion according to Mohr-Coulomb
You can find more information about this material model and the definition of the input in RFEM in the corresponding chapter of the online manual for the Geotechnical Analysis add-on.

In the Geotechnical Analysis add-on, the Hoek-Brown material model is available. The model shows linear-elastic ideal-plastic material behavior. Its nonlinear strength criterion is the most common failure criterion for stone and rocks.
You can enter the material parameters using
- Rock parameters directly, or alternatively via
- GSI classification.

A graphical and tabular output of the results for deformations, stresses, and strains helps you when determining the soil solids. To achieve this, use the special filter criteria for targeted selection of results.
The program doesn't leave you alone with the results. If you want to graphically evaluate the results in the soil solids, you can use the guide objects. For example, you can define clipping planes. This allows you to view the corresponding results in any plane of the soil solid.
And not just that. The utilization of result sections and clipping boxes facilitates the precise graphical analysis of the soil solid.
You already know that it is possible to model and analyze a soil and a structure in the entire model. As a result, you have explicitly taken into account the soil-structure interaction. By modifying a component, you achieve the immediate correct consideration in the analysis as well as in the results for the entire system of the soil and structure.
