Geotechnical Simulation: Finite Element for Soil and Rock Mechanics

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

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.

Geotechnical Analysis Include:

  • In-situ stress and pore-pressure initialization
  • Construction staged analysis
  • Drained/undrained analysis
  • Seepage analysis (steady state/transient)
  • Saturated or partially saturated flow
  • Consolidation analysis (full coupled stress-flow analysis)
  • Pressure dependent degree of saturation
  • Freely moving phreatic surfaces
  • Porosity or saturation dependent permeability
  • Deformation dependent density and porosity
  • Dynamic (linear and nonlinear) and liquefaction analysis
  • Special (embedded) pile elements with nonlinear pile shaft and toe interfaces
  • Anchors, nails, and rock bolt modelling
  • Geotextiles
  • Strength reduction analysis (phi-c)
  • Engineering liquefaction
