Defining a user-defined amplitude curve

Use the user definition method to define the amplitude curve in user subroutine UAMP (Abaqus/Standard) or VUAMP (Abaqus/Explicit). For more information, see Defining an amplitude via a user subroutine.

  1. Display the Edit Amplitude dialog box as described in Selecting an amplitude type to define.

  2. In the Number of variables field, enter the number of solution-dependent state variables that must be stored with this amplitude definition.

  3. Define the amplitude in user subroutine UAMP (for Abaqus/Standard) or VUAMP (for Abaqus/Explicit). See the following sections for more information:

  4. Click OK to save your amplitude definition and to close the Edit Amplitude dialog box.
