Using the MATLAB PDE Toolbox (or equivalent), develop an FEM solution for the stress concentration problem under biaxial loading given in Exercise 8.25. Compare the stress concentration factor from the numerical results with the corresponding analytical predictions.

Data from exercise 8.25

Using superposition of the stress field (8.4.15) given in Example 8.7, show that the problem of equal biaxial tension loading on a stress-free hole as shown in the figure is given by Eq. (8.4.9).
