1. Write a short note (not more than half A4 page) on your understanding on St. Venant's Principal for your engineering design analysis.
2. Estimate the " Stress Concentration Factor" Kt at raisers that you can identified in Figure 2 for anapplied uniform tensile forces parallel to the x -axis . Perform appropriate 2D and 3D analysis. You must compare your FEA answers (2D and 3D) with the design hand books/standards. Please note to reference your work appropriately. Choose l, h , L, H appropriately and justify your choice.
[You need to create ate a cores mesh first and a refined mesh later. Check the time taken for solution, number of elements in the mesh and the difference of your results and the time and memory taken for the analysis. Write your conclusion(s) for each 2D and 3D cases.]
