Document Summary

So, we got tankers and shit like that. Tankers and boilers and things that hold a fluid. So that"s like a big metal thing holding a fluid. Well because of the nature of a fluid, this fluid will exert a pressure force outwards on the holding material in all directions. That pressure force is causes a normal stress upon the material. This is hard to analyse, but we can simplify it by analysing it as a "thin wall" Thin wall refers to the ratio of the vessel"s inner radius, to it"s thickness. Something is thin walled if the ratio of the vessel"s inner radius (where the fluid is stored) to it"s thickness is greater than or equal to 10. Due to some derivation due to how the material is in equilibrium (b/c it"s not exploding) we end up with the following.
