SMAP-S2 is an advanced two-dimensional, static,
finite element computer program developed for the geometric and
material nonlinear structure-medium interaction
analysis.
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
rock quality.
Features
- 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.
Output
Data
Analysis results are saved numerically in a
number of different output files for displacements, stresses,
strains and section forces.
Following graphical outputs are
available:
- 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
element.
- Histories of displacements, stresses and
strains at selected nodes and elements
