Suggestions for an Advanced Constitutive Model in FEM-Based Dynamic Slope Stability Analysis

Dear colleagues,

I am planning to conduct a dynamic stability analysis of a slope using the finite element method (FEM). I intend to implement the analysis through coding and utilize an advanced constitutive model to capture the soil behavior accurately.

I am looking for recommendations on which constitutive model would be suitable for this purpose. The key requirements are:

The model should have a well-documented formulation, including all governing equations.
It should be feasible to implement within a FEM framework through coding.
I would greatly appreciate any suggestions or references to models that meet these criteria.

Best regards,
