UNA is a finite element program for static and dynamic structural
analysis. The program is capable of performing the following tasks on large FE
models:
·
Static Analysis |
·
Modal Analysis |
·
Elastic Buckling |
·
Substructuring |
·
Transient Response |
·
Frequency Response |
·
Random Vibrations |
·
Aeroelastic Response |
The UNA software is used for analysis of metal, non-metal and multilayered composite structures.
The following is a brief summary of the program
capabilities:
Element Library:
Rod, Bar, Beam,
Membrane, Plates and Shells (TRIA and QUAD), Shear, Solids, Spring,
Mass, Damper, Aerodynamic Strip, Super Element.
Loads:
Static and dynamic
grid forces and moments, Static and dynamic pressure and distributed loads,
Inertia and Rotational loads, Thermal loads, Frequency response dynamic
excitation, Random response power spectral density, Aerodynamic gust load.
Materials:
Isotropic,
Orthotropic, Multilayered Composites.
Coordinate Systems:
Basic
system. Local systems -
Rectangular, Cylindrical, Spherical.
Analysis Output:
Displacement,
velocity, acceleration, reactions, stresses, internal loads, grid point force balance – static, dynamic, complex
frequency response, power spectral density, root mean square values. Eigenvalues – frequencies and buckling multipliers, modal shapes.
Various stress values – normal, shear, von-Misses, principal stresses.
Composite material failure criterions for tape and fabric: max stress or
strain, quadratic stress or strain, Hashin stress or strain, Tsai-Hill.
Numerical
Procedures:
Sparse
linear matrix solver. Sparse
Lancos eigenvalue solver. Optimal grid sorting.
Automatic elimination of local singularities. Weight, inertia and center of gravity calculation.
Pre/Post
Processing:
Interface with
FEMAP, PATRAN, I-DEAS, NASTRAN. Converts FEM models created by FEMAP,
PATRAN, I-DEAS to the standard UNA input file. FEM output is written in
standard UNA output format, plus in FEMAP, PATRAN and I-DEAS formats for
further visualization.
