First, let's begin by finding the average stress, the nominal area stress, and the maximum stress with a concentration factor.

Although there is no analytical solution for a nite plate with a hole, there is empirical data available to find a concentration factor. Using a Concentration Factor Chart (3250 Students: See Figure 4.22 on page 158 in Deformable Bodies and Their Material Behavior), we find that d/w = 1 and thus K ~ 2:73 Now we can find the maximum stress using the nominal stress and the concentration factor
sigma_r
Now, let's look at the radial stress varies in the plate:
