1. Make a plot of the mesh.
2. Make a plot of the deformed shape. Include the undeformed shape in the same plot. Using this plot, discuss whether you have applied the boundary conditions correctly.
3. Compare the displacement at the right edge with a back-of-the-envelope estimate.
4. Make a plot of the Sigma_xx variation in the bar. Deduce the stress concentration factor for the hole on the right from this plot. Compare this to the theoretical value for a small hole in an infinite plate.
5. Determine how your stress concentration factor changes when you use a different mesh. Indicate the number of nodes and elements for your two meshes. Also, include a plot of your second mesh.

Tips:

1. You need to constrain your ANSYS model adequately so that it doesn't fly off to Europa. The figure above doesn't specify any displacement constraints but you can make use of symmetry to impose displacement constraints.

2. You can save a copy of a plot using the following icon in the top menu:

Or you can use the Snipping Tool in Windows 7.

23. If you apply pressures to both the right an left edges, you'll get an error saying that the model is insufficiently constrained. You need to have a displacement constraint to overcome this. So constrain the left edge in the x direction and apply the pressure on the right edge.
