During a forming process, the elasto-plastic stress gradients across the surface build up and result in accumulation of residual stresses. The residual stresses cause the material to bounce back after forming. The resulting deviations from the profile often require manual adjustment before the component is considered acceptable for assembly. Components that do not fit in the final assembly usually need additional shimming and assembly time.

This tutorial teaches you the setup procedure for performing a springback analysis. The part-shape and stress-and-strain states at the end of a simple draw forming operation are the inputs to the setup and are available in the STA file. Appropriate material and section properties are assigned to the blank component.


1.The file for this tutorial, radios_springback_sta, is zipped in the file, Copy and unzip the file,, into your working directory.

Note: The model files for this tutorial are located in the file in the subdirectory \hf\Incremental\. See Accessing Model Files.

2.On the bottom of the tree in the User Process, right-click Blanks, select From File..., browse to the file radios_springback.sta, and then click Open.

The file loads and the model is displayed in the graphics area on your screen.

3.At the top of the tree, right-click Process Type, and then select Springback.
4.Under Blanks, right-click Material, and then select Database…. The Material Database dialog appears.
5.In the Steel folder, click CRDQ, and then click Select.
6.At the top of the tree, right-click Process: Springback, and then select Run.
7.At the prompt that appears, select Yes.
8.In the dialog that appears, browse to your working folder, for File name, enter a file name, and then click Save.

The RADIOSS implicit solver launches and runs the springback computation.
