SMAP-S2 is an advanced two-dimensional, static,
finite element computer program developed for the geometric and
material nonlinear structure-medium interaction
The program has specific applications for
modeling geomechanical problems associated with multi-staged
excavation or embankment.
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
- 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
- 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
- Truss element allows yielding, buckling and
post-buckling. It can be used for rock bolts and anchor
- 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.
Analysis results are saved numerically in a
number of different output files for displacements, stresses,
strains and section forces.
Following graphical outputs are
- Finite element mesh and Deformed shape
- Principal stress distribution
- Contours of stresses and strains
- Section forces, extreme fiber stresses and
strains in beam.
- Axial forces, stresses and strains in truss
- Histories of displacements, stresses and
strains at selected nodes and elements
