How to calculate bending stress
Thread Content
It is a vertical device consisting of a simple convex head and cylinder nozzles. Question: Are there bending stresses in the cylinder and the head? (Practical application: in low-temperature and low-stress conditions, \"under these design conditions, the maximum tensile stress and bending stress experienced by the container components are less than or equal to 1/6 of the yield strength of the steel material at normal temperature\")

The bending stresses on vertical containers can be used as an analogy for stress analysis in towers. Bending stresses may be caused by wind loads, lateral forces on the load, eccentric loads, etc. Depending on whether it’s a cylinder or a pipe, the stress levels are likely to be low. Wind loads and such forces don’t seem to be taken into account in container calculations, and only you know if eccentric loads are a factor. In my opinion, the more dangerous stresses are likely the circumferential stresses, as well as the axial stresses resulting from the combination of pressure, weight, and bending stresses
Has your problem been solved? Could you share the calculation process and the factors taken into consideration?
During operation, under the action of internal and external pressures, the cylinder and the head experience constraint stresses due to inconsistent free deformation, which keeps them connected to each other; as a result, there is a constraint torque, and bending stresses are also generated
With such low temperatures and low stresses, the bending stress is very small and can be ignored. Moreover, the very important seismic issues in the chemical industry have been ignored; sigh, how is it possible to live like this? . .
