Using the MATLAB PDE Toolbox (or equivalent), develop an FEM solution for the stress concentration problem under shear loading given in Exercise 8.26. Compare the stress concentration factor from the numerical results with the corresponding analytical predictions.

Data from exercise 8.26

Using superposition of the stress field (8.4.15), develop solution (8.4.18) for the equal but opposite biaxial loading on a stress-free hole shown in Fig. 8.15A. Also justify that this solution will solve the shear loading case shown in Fig. 8.15B. Construct a polar plot (similar to Fig. 8.13) of σθ(a,θ)/T for this case.
