SUMMARY
The discussion focuses on determining the necessary thickness of a hollow sphere made from a high elasticity constant material, such as steel, to withstand atmospheric pressure when the air inside is evacuated. The use of Lame's solution and Finite Element Analysis (FEA) is considered valid for quantifying the required thickness. The problem involves stability and buckling, highlighting the challenges of manufacturing a perfectly shaped sphere with uniform shell thickness and welds. Calculations must incorporate a generous safety margin to account for internal stresses and potential uneven deformation.
