Description
GFAS is a two-dimensional (2D) finite element software for non-linear analysis in geotechnical engineering. The plastic constitutive models available are full and modified Mohr-Coulomb, Von Mises, Drucker-Prager, structural elements: Beam, Pile, Anchor, Bold and Geosynthetics. With GFAS is also possible to carry out dynamic modal analysis of soils and water flow analysis.
In non-linear analysis, Construction phases, Bearing capacity and Slope stability can be examined. All analyzes can be conducted in static and dynamic conditions. The dynamic modal analysis is performed based on: design spectrum, soil type, damping etc. The groundwater can be considered at the calculation level in a steady-state flow regime with a flow net.
The software offers a database of integrated templates for the generation of:
-
- Tunnels;
- Excavations;
- Slopes;
- Foundations;
- Reinforced Earth.
- Tunnels;
G.F.A.S. (Geotechnical and F.E.M. analysis System) is a complete solution that integrates all functions required for the mechanical analysis of soil using the finite element method.
MATERIALS MODEL
-
- Linear and non-linear elastic model;
- Mohr-Coulomb failure criterion.
AUTOMATIC MESH GENERATION
The program automatically generates the mesh with triangular elements and refines at points of particular interest, such as edges, load areas, kinematical constraints, etc.
BOUNDARY CONDITIONS
It is possible to assign boundary conditions on displacements or rigidity.
LOADS
Loads can easily be assigned with the mouse in any mesh node.
RESULTS
Results can be easily displayed numerically or graphically with stress and deformation indications.
