Hi everyone,
I'm designing a vessel of ~1m[sup]3[/sup] supported by 4 lugs to horizontal structural members (It contains water at 35°C). Due those, the shell should have a local stress concentration in each lug, with a bending moment and shear stress.
Despite the ASME code, section VIII classifies this as a local primary membrane stress, i don't get to see how to calculate the thickness of the shell to resist the bending moment produced by its own weigth.
Is there any equation, method or rule to follow to calculate the thickness of the vessel? I do not need an exact result, but what i do need is an idea of how much the thickness should be to support itself
I'm sorry for my english, hope the question is understood.
Thanks!
