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
