Geometry / Mesh

Before we look at the solution, lets look at the mesh. It is below.

The first thing to notice about the plate with the hole geometry is that the domain is only a quarter of the full plate. Because there are two symmetries (x plane and y plane), the geometry can be reduced to 1/4 of the original, simplifying the solution. The domain is then separated into several subdivisions, called "elements". For each element, ANSYS approximates how each element responds to the forces and constraints acting on the domain. For areas where a concentration is likely (i.e. the hole in this situation), the mesh is refined for more accurate results.

Displacement

Okay! Now we can check our solution. Let's start by examining how the plate deformed under the load. Before you start, make sure the software is working in the same units you are by looking to the menu bar and selecting Units > US Customary (in, lbm, lbf, F, s, V, A). Now, look at the Outline window, and select "Total Deformation" under "Solution"

The colored section refers to the magnitude of the deformation (in inches) while the black outline is the undeformed geometry superimposed over the deformed model. The more red a section is, the more it has deformed while the more blue a section is, the less it has deformed. Notice that the deformation is at its highest where the load is applied, and there is no a lot of variation in the y-direction, as one intuitively expect.

Now lets examine the stress in the x-direction. Look to the Outline window, then click Solution > Sigma-X
