>>12715787>If you look at the properties of a high-quality 304L stainless steel, at cryogenic temperatures the strength is boosted by 50 percent.so when the long fuselage does its acrobatics and the fuselage-length bends and the stress is dissipated by its flexibility, does it not experience metal fatigue?
yes it does.
so instead of the weakpoint being at the center of these colder rings where the fuel level is... its at the seam's boundaries instead..
*the seam is stronger than the rest of it.
if you can physically see a colder (therefore more tensile seam) then why would you think the entire tank was a homogeneous temperature with the same tensile strength?
the bending fuselage will cause metal fatigue at the seam boundaries.
those welding joints are retarded.
should of gone with seamless welding, instead... oops silly me, that doesn't work on tin cans.
