Elastic Properties (FEA)
Elastic parameters used by the experimental finite-element analysis.
Experimental
Elastic properties are used only by the experimental finite-element analysis (FEA). They have no effect on standard limit-equilibrium (Bishop, Janbu, Spencer, GLE) results.
Each material carries two linear-elastic parameters, edited on the FEA tab of the Define Material Properties modal.
Parameters
| Parameter | Unit | Default | Range | Description |
|---|---|---|---|---|
| Young's Modulus (E) | kPa | 30000 | > 0 | Elastic stiffness of the material. |
| Poisson's Ratio (nu) | — | 0.3 | 0–0.499 | Ratio of lateral to axial strain. Capped below 0.5 to keep the material compressible. |
Where they are used
These parameters feed the experimental FEA paths only:
- Elastic stress field — the finite-element elastic stress solve that produces in-situ stresses used by the FEA-based slice strength evaluation.
- FEA-elastic interslice function — an interslice force function derived from the elastic stress field, available as an option to the rigorous solvers.
Because both consumers are experimental, leaving the defaults in place is appropriate for routine limit-equilibrium analyses; they do not change those results.
