Objectives 1. Set up COMSOL for conducting an FE structural analyses of displacement of a square plate with a hole at the center subject to tension. 2. Generate the base displacement solution using the self-generated mesh. 3. Conduct a uniform mesh refinement study, hence note that the solution is diverging at the plate corner wall attachments. 3. Alter the wall displacement BC to contraain only the u displacement, observe solution convergence, then verify the engineering accuracy of this solution via a mesh refinement study. 4. Via a set of computational experiments, determine the shape of a non-circular hole of the same area as that given that minimizes the maximum stress concentration throughout the plate measured in the von Mises stress.
