FORMING LIMIT CURVE

 

The functions in this menu are used to create, read, and display the FLD curve of the materials.  The dialog window is shown in Figure 9.8.6. These options are similar to those described in Section 12.9, UTILITIES/LOAD CURVE.

Note: There are three different curve formats that are supported by eta/DYNAFORM; i.e. these curve formats can be read into an eta/DYNAFORM database.
