software - SMAP-S2

Following graphical outputs are available:

Analysis results are saved numerically in a number of different output files for displacements, stresses, strains and section forces.

Output Data

• Continuum element allows 2-D plane strain, plane stress and axisymmetric analyses. It can be used for soils, rocks and concrete media. Material yielding and tension-cutoff are considered.
• Joint element allows separation and sliding along the interface. It can be used for modeling rock joints, fault zones, or structure-soil interfaces.
• Beam element allows axial, bending and shear deformations. It can be used for rectangular or tee-shape reinforced concrete or composite beams. Cracking and crushing of concrete and yielding of the reinforcing bar are considered.
• Truss element allows yielding, buckling and post-buckling. It can be used for rock bolts and anchor bars.
• SMAP-S2 contains automatic node renumbering scheme to reduce bandwidth.
• Updated Lagrangian Formulation is used to model large deformations.
• SMAP-S2 is capable of solving up to 99,990 elements or nodes.
• SMAP-S2 contains several pre-processing programs which can be used to generate nodal coordinates, boundary constraints, element indexes, and applied loads for continuum, beam and truss elements.

The material models in the program include Von Mises, Mohr-Coulomb, Drucker-Prager, and In Situ Rock models. The In Situ Rock model incorporates the Hoek & Brown empirical data base tabulated for several different rock types as a function of rock quality.

The program has specific applications for modeling geomechanical problems associated with multi-staged excavation or embankment.

SMAP-S2 is an advanced two-dimensional, static, finite element computer program developed for the geometric and material nonlinear structure-medium interaction analysis.
