On the calculation of externally pressurized vessels
Thread Content
In GB150, two coefficients, A and B, are involved in the calculation of the external pressure on the cylinder. Someone asked yesterday what the meaning of these two coefficients is respectively. I know how to find this coefficient, but I’m not clear about what it actually means. Please give me some guidance! :)
It should be a problem with the circumferential welds and longitudinal welds; there is a diagram in GB150 that explains this
Value A represents the circumferential strain of this cylinder under critical external pressure, while value B is numerically equal to twice the allowable circumferential compressive stress for the stability of the cylinder. Plots using A and B represent the tensile mechanical properties of a certain material.
