eta/DYNAFORM is an LS-DYNA-based sheet metal forming simulation solution package developed by Engineering Technology Associates, Inc. The specialty CAE software combines the sheet forming analysis power of LS-DYNA Versions 971 with the streamlined pre- and post-processor functions.


These analysis codes and interactive functions are uniquely integrated to service the sheet metal forming industry in tooling design and development, which helps designers reduce tooling development time and tryout lead-time.With its superior usability and intelligent tools, eta/DYNAFORM can easily solve all kinds of sheet forming problems. The program also maximizes traditional CAE techniques to reduce prototyping costs and lead time for product development.

eta/DYNAFORM’s analysis engine is LS-DYNA, which is developed and currently supported by the Livermore Software Technology Corporation (LSTC) of Livermore, California. It is a general purpose, non-linear, dynamic, finite element analysis code utilizing explicit and implicit capabilities for solving fluid and solid structural problems. The code has been developed for applications such as automobile crashworthiness, occupant safety, underwater explosion, and sheet metal forming.

The bottleneck of the metal forming development cycle is the hard tooling design lead-time. The eta/DYNAFORM CAE approach simulates this tooling process and thereby reduces the tooling tryout time and the associated cost for producing high quality stamped parts. eta/DYNAFORM effectively simulates the four major design concerns in the tooling process: Binder Wrap, Draw Die, Springback, and Multiple Stage Tooling. These simulations enable engineers to conduct feasibility studies of a product design early in the design cycle.

eta/DYNAFORM features well-defined tooling surface data to predict the performance of a stamping for areas such as Tearing, Wrinkling, and Thinning, in addition to predicting Skid Mark and Springback effects.

Release Notes DYNAFORM 5.8.1
Major improvements

1. Streamlined the BSE interface.
2. In the DFE module, the user can now parametrically build the die face for a symmetrical part.
3. Added new product change replacement functionality. The user can easily retain the current die face design and drop in new product design surfaces.
4. Added the ability to support a user defined ‘Geometry Drawbead’ and ‘Line Bead Conversion Library’
5. In “AutoSetup”, added the standard nitrogen cylinder force curve library for binder control.

Newly Implemented Capabilities, Features and Functions in the BSE Module

1. Added a new BSE project interface, which allows the user to set unit, material density and sheet type before analysis and calculation.
2. Added the ‘Auto Mesh’ option in the “Preparation Import” dialog to mesh the CAD model immediately after it is imported.
3. In the "Generate Middle Surface" function within the “Preparation” menu, the program now automatically adds the middle surface layer to the current tool. It also removes other layers from the current tool after the middle surface is generated.
4. Added the ability to add the top and bottom surface layers of the part to the current tool and remove other layers in the current tool after the "Separate Surface" function in the “Preparation” menu.
5. The “MSTEP” mesh is now set as the default in the “Preparation” menu’s "Surface Mesh" function.
6. Added a "Symmetry" function, which automatically checks the symmetry, based on the defined symmetry plane.
7. Added a new function for automatically adjusting the stamping direction in “Tipping”, called “Element Normal”. The average normal for the selected mesh is applied as the stamping direction.
8. Improved the “Double Attach”, “Inner Fill” “Boundary Smooth” and “Sidestep” functions. Refer to the DFE module for descriptions.
9. The “MSTEP”, “Outline” and “Nesting” functions are now integrated into one dialog box arranged in tabs, allowing the user to easily switch among these functions.
10. “Draw” and “Trim Line” in “MSTEP” are now separated, allowing the user to configure them individually.
11. Improved the "Generate Outline" function in “MSTEP”.
12. Added the "Select All Parts" option in “Define Sheet Material” of BSE, allowing the user to define the material property for all the selected parts.
13. Added the ability to define the "Boundary Condition", by region, for “MSTEP” outlines.
14. Streamlined the “Nesting” interface.
15. Added the ‘Free’ option so the user can manually adjust the blank.
16. Added the ‘In One Row’ option in the “Constraints” menu for "Two-Pair" and "Mirror" to display the nesting results in one row.
17. After adjusting the step under “Draw nesting type”, the trim line now automatically returns to the original position after finishing the operation in “Calculate 3D”.
18. Added the "Plate" nesting function, allowing the user to constrain the nesting result through
the definition of blank length and width.
19. Removed the "Batch MSTEP" and "Batch Nesting" functions.
