As with any numerical method verification and validation of great significance. As mentioned earlier, there is no analytical solution for the finite plate with a hole. Thus, the results can not be compared to theory. Thus, in this section other verification and validations will be used. First, the solution will be examined as the mesh is refined to see if it has converged. Additionally, the optimization results will be verified by using different optimization methods and comparing results.

Optimization Methods


The optimization was carried using each of the four optimization methods offered in ANSYS workbench. Note that the default optimization method in ANSYS is Screening.

Optimization Method

Radius (In)

Volume (In^3)

Equivalent Von Mises Stress (PSI)
