Geotechnical and F.E.M. analysis system – GFAS

890.00 esc. IVA

G.F.A.S. (Geotechnical and F.E.M. analysis System) software for the mechanical analysis of soil using finite elements method .

The traditional methods of analysis based on the concept of LIMIT EQUILIBRIUM (LEM) do not allow the determination of stresses and deformations in the analyzed volumes. These limitations have led to the need to integrate the conventional analysis with analysis based on numerical models. These methods use the numerical evaluation of the problem and do not require simplifications to the calculation.

GFAS Extension brings additionial features to the finite element software like waterflow analysis. See product.

 

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 can be examined: Construction phases, Bearing capacity and Slope stability. All analyzes can be conducted in static and dynamic conditions. The dynamic modal analysis is performed on the basis of: design spectrum, soil type, damping etc. The groundwater can be considered at the calculation level in a steady-state flow regime with flow net.

The software offers a database of integrated templates for the generation of:
Tunnels
Excavations
Slopes
Foundations
Reinforced earth

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 finite elements method.

MATERIALS MODEL 
• Linear and non linear elastic model
• Mohr-Coulomb failure criterion

AUTOMATIC MESH GENERATION
The mesh is generated automatically by the program with triangular elements and subsequently refined 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 node of the mesh.

RESULTS
Results can be easily be displayed either numerically or also graphically with indications of stress and deformation.
