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