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.
