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-Prage; 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:
• 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.
• 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.
It is possible to assign boundary conditions on displacements or rigidity.
Loads can easily be assigned with the mouse in any node of the mesh.
Results can be easily be displayed either numerically or also graphically with indications of stress and deformation.
