mechanical engineering project and need the explanation and answer to help me learn.
1) Create a file containing figures for each mesh for the x-stress zoomed into the notch region.
2) Submit a picture of the refined solution with its mesh and explain how many iterations were required to converge along with any differences between these results and those you had previously.
3) Complete Exercise #1 which begins on page 3-38. Create a PDF file documenting your exercise results. Be sure to compare your finite element results to calculated values. Note that in the modeling portion, Kt for the hole should be computed using the proper table in the Appendix C of Norton’s book. For fully reversed loading, estimate the maximum force, F, which could be applied to the 2018-T6 aluminum (same as in Solidworks material library) with a fatigue safety factor of 2.0.

MME 342 Lab 3 Mesh Refinement Applied to Stress Concentrations Background Proper mesh refinement (more and smaller elements which introduces more nodes) verification is essential before finite element analysis can be used for anything, even for simple cases. Once the geometry and loading has been confirmed, the idea is to continue to refine the mesh until stress components at key locations no longer change with further mesh refinement. Any finite element results used for design are assumed to have been established only after an acceptable mesh refinement procedure. This process is entirely the responsibility of the finite element analyst. Proper mesh refinement removes mesh uncertainties from the many common machine design parameters. Objectives After this lab students will be able to: 1) Retain only key attributes of a solid model to simplify finite element modeling. 2) Perform mesh refinement correctly. 3) Accurately predict stress levels in various geometries, including concentrations. Procedure 1) Follow the steps given in Chapter 3 of Reference 2 from page 3-1 to 3-36. From this work, create a file containing figures like Figure 11 on page 3-10 for each mesh for the x-stress zoomed into the notch region. Also include a completed table like discussed on page 3-10 and shown Table 2 on page 3-34 with von Mises, x-stress, displacements, and number of nodes/elements. Include a graph like that in Figure 40 on p. 3-35. Your stress contour plots must verify x-stress values shown in your table and be compared to hand calculations as found on pages 3-36 to 37. Include a brief paragraph describing what you learned about mesh refinement as well as stress concentrations. 2) Right click on the ‘Static 1 (-Default-) item on the top of the geometry tree. Select ‘Properties…’ from the pulldown menu. Select the ‘Adaptive’ tab. Choose ‘h-adaptive’, set the ‘Target Accuracy’ to 99%, ‘Maximum no. of loops’ to 5, and select the ‘Mesh coarsening’ box. Then click ‘OK’ and rerun your model. Submit a picture of the refined solution with its mesh and explain how many iterations were required to converge along with any differences between these results and those you had previously. 3) Complete Exercise #1 which begins on page 3-38.
