SMAP-S2 and SMAP-S3
Structure Medium Analysis Program
Static Finite Element Analysis
Both SMAP-S2 and SMAP-S3 are advanced static finite element programs
for geometric and material nonlinear structure-medium interaction analysis.
Both programs have specific applications for modeling geomechanical problems
associated with multi-staged excavation or embankment.
SMAP-S2 is the 2-dimensional version which takes account of plane stress,
plane strain and axisymmetry configurations.
SMAP-S3 is the 3-dimensional version which takes static portion of SMAP-3D.
Refer fo features of SMAP-3D.
The material models in SMAP-S2 include Von Mises, Mohr-Coulomb,
Drucker-Prager, and In Situ Rock models. The In Situ Rock model incorporates
the Hoek and Brown empirical data base tabulated for several different rock
types as a function of rock quality.
Features of SMAP-S2
-
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, T-shape or I-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.
-
Ii contains automatic node renumbering scheme to reduce bandwidth.
-
Updated Lagrangian Formulation is used to model large deformations.
-
It is capable of solving up to 99,990 elements or nodes.
-
It 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 from SMAP-S2
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, strains and displacements
- 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
