You can create an initial stress field for a region of your model. You can create or modify an initial stress field only in the initial step. For more information, see “Initial conditions in Abaqus/Standard and Abaqus/Explicit,” Section 34.2.1 of the Abaqus Analysis User's Guide.
To create or edit a stress field:
Display the stress field editor using one of the following methods:
To create a new stress field, follow the procedure outlined in “Creating predefined fields,” Section 16.8.3 (Category: Mechanical; Types for Selected Step: Stress).
To edit an existing stress field using menus or managers, see “Editing step-dependent objects,” Section 3.4.13.
Note: You can create or edit a stress field only in the initial step.
Click the arrow to the right of the Specification field, and select the option of your choice from the list that appears:
Select Direct specification, then specify stress components in the data table. You can specify up to six component values.
Select From output database file to specify stress values from a user-specified output database file.
If you are specifying initial stress from an output database file, do the following:
Specify the file name from which you want to import stress values.
From the Step and Increment fields, specify the step name and increment number from which you want to import stress values.
Click OK to create the initial stress field and to close the dialog box.
Blue circles appear on the model representing the initial stress field that you just created.
