4. Repeat the previous step to enter the following Strain/Stress value pairs: 0.002562402, 25.08; 0.004471788,
   29.07; 0.006422389, 31.73.


5. Click on OK.


6. Choose menu path Material> Exit to remove the Define Material Model Behavior dialog box.

8.13.3.5. Label Graph Axes and Plot Data Tables

1. Choose menu path Utility Menu> PlotCtrls> Style> Graphs> Modify Axes. The Axes Modifications for
   Graph Plots dialog box appears.


2. Enter Total Strain for the X-axis label.


3. Enter Tr ue Stress for the Y-axis label and click OK.


4. Choose menu path Main Menu> Preprocessor> Material Props> Material Models. The Define Material
   Model Behavior dialog box appears.


5. In the Material Models Defined window, double-click in Material Model Number 1, and Multilinear Kin-
   ematic (General). The dialog box appears that includes the Strain/Stress data pairs that you entered.


6. Click on the Graph button. A graph of the data table values appears in the Graphics window. If necessary,
   re vise the stress/strain values and click on the Graph button again. Repeat revisions and graphing as
   needed until you are satisfied with the graphed results. Click on OK.


7. Choose menu path Material> Exit to remove the Define Material Model Behavior dialog box.


8. Click on SAVE_DB on the Toolbar.

8.13.3.6. Create Rectangle

1. Choose menu path Utility Menu> Parameters> Scalar Parameters. The Scalar Parameters dialog box
   appears.


2. Type "radius=1.0" in the Selection field and click Accept. This value is the radius of the plate.


3. Type "thick=0.1" in the Selection field and click Accept. This value is the thickness of the plate. Click
   Close.


4. Choose menu path Main Menu> Preprocessor> Modeling> Create> Areas> Rectangle> By Dimensions.
   The Create Rectangle by Dimensions dialog box appears.


5. Enter "0, radius" for X-coordinates.


6. Enter "0, thick" for Y-coordinates and click on OK. A rectangle appears in the Graphics window.


7. Choose menu path Utility Menu> Plot> Lines.

8.13.3.7. Set Element Size

1. Choose menu path Main Menu> Preprocessor> Meshing> MeshTool. The MeshTool dialog box appears.
