Example 1: 2-D Static Stress Analysis in ANSYS
In this example we will examine the stress concentrations in a flat plate with three holes, as shown in
Figure 1.1.

Preprocessor
First, we will select an element type, define element and material properties, create a model, and mesh it in
the Preprocessor.
Selecting an element type:
1. Click on ‘Preprocessor’ in the ANSYS main menu at the left side of the screen.
2. Click on ‘Element Type-Add/Edit/Delete’.
3. Click ‘Add’.
4. Choose ‘Solid’ from the ‘Structural’ list of element types, then ‘Quad 4node 42’ from the list on the
right. This chooses a four-node quadrilateral 2D element.
5. Click ‘OK’, then click ‘Close’ on the Element Types box and close the Element Types menu.
Defining material properties:
1. Click ‘Material Props’ in the Preprocessor menu.
2. Click ‘Material Models’.
3. Double-click ‘Structural’ in the right side of the window, then ‘Linear’, then ‘Elastic’, then finally
‘Isotropic’.

4. Enter in values for Young’s modulus and Poisson’s ratio. In this problem we use a Young’s modulus of
70e9 and a Poisson’s ratio or 0.3, which are ballpark values for aluminum (note that ANSYS understands
scientific “e” notation). No other material properties will be needed, so click ‘OK’, t
