Stress2D
Engineering Stress Analysis of 2D Problems
Stress2D is a software package for engineering stress analysis of 2D problems. The program provides an easy solution for a specific structural design problem. The loading can be arbitrary line loads, point loads and volume load (gravity, inertia, etc.). The loading is applied in up to ten basic load cases. The basic load cases can be combined in ten additional load combinations. The results are given as deformed shape for each load case and load combination. Stress contours are also provided.
Key Features:
- Deep beams/walls steel design
- Based on well-established Finite Element approach
- 3-node and 4-node panels for easy input of any geometry
- Axial bars (truss elements)
- Fixed and elastic supports
- Plane Stress and Plane Strain problems
- Point Loads, Line Loads and Volume Load in up to 10 Load Cases
- DXF and Bitmap import
- Deformed Shape Results
- Stress Distribution and Principal Stresses at any point
- Reaction in all fixed and elastic supports
- Stress integration, extract M, Q and N (see below)
-
The program runs on a PC computer under, Windows 95, 98, 2000, NT, XP, and Vista.
The solution algorithm is based on Linear Elastic - Finite Element Method. The software employs six-node Linear Strain Triangular (LST) elements. Finite element mesh generation and node numbering is performed automatically. The automatic meshing facility allows easy generation of a very fine mesh.
Modelling of the geometry and results presentation is fully interactive, taking advantage of the graphical Windows environment. All the results are presented graphically for an easy and quick review.
There are three alternative editing methods for definition of the model:
- Graphical Editor (includes even and custom grid)
- DXF Import (from any CAD program
- Bitmap Import (from scanned images)
Interface
It is Different ...
No Elements , No Nodes, No Freedoms... No Problems !
Stress2D software is conceptually different from any other Finite Element software. Its was designed to be used by ordinary practicing engineers, non-specialists in finite elements analysis. Simply, the user defines the geometry by subdividing the area in 4-node and 3-node polygons, without defining any nodes or elements connectivity. The software will generate and number the nodes, generate the finite elements and connect the elements' degrees of freedoms to the nodes. The mesh generation is fully automatic, and does not need any intervention from the user. This operation is monitored at the background, to prevent some common modelling problems at a very beginning. This concept was first introduced in our software product SLABS, and it is widely accepted by hundreds of engineers.
The results are presented in a graphical way, as deformed shape, and contour lines for stresses. The unique "Integrate" function can be used to extract M, Q and N, which can be used to check or design the sections. (more...)
All this makes Stress2D a must-have software package for any structural engineer.
