Recalculating Stress
Before recalculating the stress division of the lever, calculate and display the
deformation.
To calculate the stress
1 To restart the FEA routine, on the command line. enter AMFEA2D.
2 Respond to the prompts as follows:
Specify interior point: Specify a point inside the contour
Select the thickness and the material of the lever again, as you did it
before.
3 In the Default section, enter a thickness of 10.
4 Click Table, and select the material from your preferred standard table.
Select Al. Alloys Diecast if you prefer to use ANSI materials.
5
Click the deformation button in the Results field.
6 In the FEA 2D - Displacements dialog box, Click OK.
7 Respond to the prompts as follows:
Specify base point <Return = in boundary>: Press ENTER
Insertion point: To the right of the part, select a location for the table
