Finglow Yeild Stress Figure
Finglow Yeild Stress Figure
(OP)
Hello,
I'm using Finglow 3D December 2013 to calculate the minimum shell thickness of a tank which is required to withstand a vacuum pressure of 100 mbar made from SS 304.
I'd like to know the figure that Finglow uses for the yield stress for BS 1501-304-S11 but cannot find it on the program.
The tank is 5mm thick but in the calculations the minimum required thickness is 5.12 mm - if Finglow is using a yield stress less than the yield stress of the material we use to build the tank then it may meet the ASME VIII requirements without having to move to a 6mm shell.
Any feedback would be greatly appreciated!
Best,
Tom

Corus, I thought the yield stress would be an important factor for tanks failing but I might be wrong. Why doesn't the yield stress come into it? I've been reading into buckling more as a failure mode but I haven't found anything highly relevant for tanks - so far I've just found examples relating to beams.
