Geotechnical Simulation: Finite Element for Soil and Rock Mechanics in Foundations, Embankments, Tunnels, Excavations, Slope Stability, Mines and Dams
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
Geotechnical applications and the interaction between the ground and structure, often provide engineers with technically demanding challenges that are best solved with special purpose finite element method software. Finite element method provides a wide range of state-of-the art constitutive models for tackling soil and rock materials in applications as diverse as foundations, embankments, tunnels, excavations, slope stability, mines and dams.
Material models suitable for soil & rock:
- Mohr-Coulomb, Tresca
- Drucker-Prager, Von Mises
- Transversely Isotropic
- Duncan-Chang
- Hoek-Brown
- Jointed rock
- Modified cam-clay
- Modified Mohr-Coulomb (cap model)
- Classic brick
- Special Interface models
- User-supplied subroutine
Soil-Structure Interaction
The proposed FEA analysis methods by Enteknograte for pore pressure and consolidation, groundwater flow, earthquake and liquefaction problems are some of the most advanced available and are essential for accurate analysis of these types of coupled problems.
Enteknograte also offers advanced techniques and methodologies based on client needs to model steel and reinforced concrete structures that interact with the ground.
