Please answer the question clearly, stating how you chose the formulas and what each variable represents. Thank you!
For the problem shown in Fig Q1(a), elastic contact stress between a cylindrical punch and a fixed base plate when a displacement (Uy) is applied can be simulated using FE method. With appropriate sketches for geometry, boundary conditions, and areas for mesh refinement of the model, outline how convergence study can be carried out for the problem. (Note: no detailed drawing of mesh is required.). Mention and justify element types to be used for the model. Describe clearly the parameter to be used for the convergence study.
