Plaxis 2d 8.6 [verified] -
PLAXIS 2D 8.6 is a legacy version of the widely respected PLAXIS 2D finite element software, primarily used for deformation and stability analysis in geotechnical engineering. While newer versions under Bentley Systems offer more advanced cloud capabilities and 3D modeling, version 8.6 remains a staple in academic research and historical project validations due to its reliability and straightforward interface. Key Features & Performance Finite-element mesh discretization of typical test sample
3.4 Calculation Types
- Plastic Calculation: Standard elastoplastic deformation analysis.
- Consolidation: Coupled deformation and pore pressure dissipation analysis.
- Safety Analysis: Phi-c reduction method for factor of safety calculation.
- Updated Mesh: Capability to handle large deformations (though refined significantly in newer versions).
Phased Calculations:
- Plastic (Null, Elastic, Plastic): For undrained or drained loading/unloading.
- Consolidation: Fully coupled Biot's theory for pore pressure dissipation.
- Safety (Phi/c-reduction): A classic strength reduction method to compute global Factor of Safety (FS). This is where v8.6 shines—it rarely suffers from non-convergence issues if the mesh is adequate.
- Note: 8.6 does not have the Hardening Soil model as default in the standard license (that came later). Do not try to use HS unless you bought the advanced module.
- Input:
E_ref = 30 MPa,Nu = 0.3,Phi = 32 deg,C = 0.1 kPa.
