FEM

Main Features

• Variety of conventional and state-of-the-art material models:
  • Linear elastic model
  • Modified elastic model
  • Mohr-Coulomb model
  • Modified Mohr-Coulomb model with hardening/softening
  • Drucker-Prager model
  • Cam Clay model
  • Hypoplastic model for clay
• Wide range of common structural elements (built-in catalogs of manufacturers):
  • Concrete walls, pile walls, soldier pile walls (Braced Sheeting) or reinforced tunnel lining are modeled by the beam elements with catalogued profiles and materials
  • Anchors
  • Nails
  • Props
  • Reinforcements (geotextiles, geogrids)
  • Built-in database of steel cross-sections (catalogs of manufacturers)
• Contacts elements between soil and structure with nonlinear stress-displacement relation
• The model consists of several construction stages to account for the construction process
• Any number of surcharges (strip, trapezoidal, line load) can be added to the model in any construction stage
• Boundary conditions are generated either automatically or defined specifically for chosen points or lines
• The ground water table is either user-defined or computed in FEM – Water Flow and imported via GeoClipboard
• Each material model can be either in drained or undrained conditions
• The stability analysis can be run in each construction stage with either static or earthquake loading providing a current factor of safety
• An extensive list of variables (settlements, stresses, strains, plastic zones, pore pressure, etc.) is plotted on either deformed or undeformed model
• The distribution of internal forces and deformation of the structural elements is available
• The evolution of quantities at chosen points is observed by the means of monitors and graphs
• Automatic mesh generator issues warnings on problematic topology parts
• The size of elements can be adjusted by point, line and free refinements
• The program supports DWG, DXF import and export
