Forming and Shaping

Metal forming is a category of metalworking process through which the material can be given the desired shape and size by subjecting it to plastic deformation, where the component undergoes bulk deformation process upon application of loads. Unlike the shearing and machining process, the material does not undergo up to a failure point as indicated in the stress-strain curve. Hence, the stresses induced during the forming process are greater than yield strength but less than the failure strength of the material. The process does not lead to the loss of material, so it can be said to be an economical process. During forming, the material is subjected to tensile forces, compressive forces, bending, and shearing loading conditions. The material should possess the property of ductility to undergo the forming process.

I need the answer as soon as possible
this cylinder has a rod inside, around the rod there is paraffin wax that will expand, I want to know how to reduce the thickness of this cylinder. However, I don't know what formulas I need to be able to do this and how to do the calculations. Please can you make an example with the data you choose to have an example of how to do this step by step? Thank you Also keep in mind that the wax is expanding by an induction coil, and the heat is happening around the cylinder. And the thickness of the stainless steel cylinder has to be thin but not so thin that it causes a pressure problem.
