Response Surface

In this step, ANSYS builds a surface from the discrete sampling points selected in the previous step. This can be thought of as building a model of the terrain in the design space.

Start by double clicking on Response Surface in the Project Schematic window. Once the Response Surface window opens click Update Response Surface. After, the update has completed click on Response to see a plot of the maximum Von Mises stress as a function of hole radius. In order to display a plot of the volume as a function of the hole radius, change the value assigned to Y axis to P3 EquivalentStressMax.

As expected, the maximum Von Mises Stress increases as the radius increases.

Volume

The first plot below which should appear shows the volume of the quarter plate as a function of the hole radius, and is shown below.

The relation between radius and volume is quite trivial to compute. It will simply be the area of the surface multiplied by the thickness of the surface. With this in mind, V=t*(h*w-(1/4)*pi*r^2) where V=volume, t=thickness, h=height, w=width and r=radius.

As expected, the maximum Von Mises Stress increases as the radius increases.

At this point, click Return To Project and then save the project.
