bracket stresses

bracket stresses

bracket stresses

(OP)
does anybody have a method of calculating stresses in pressure vessel shells due to weight loaded brackets such as structural brackets. I know about the Bednar and Megyesy methods tks  but they dont address brackets which have a A/B ratio outside the limits of 1.5  or between 1/2 and 2 respectively...

RE: bracket stresses

Bednar has line loads on a shell that can be used with brackets.

Also, Blodgett,"Design of welded structures " has a section on bracket loads on a shell.

RE: bracket stresses

As mentioned by Tankman650

Design of Weldments by Omer Blodgett
This is a very handy and outstanding book and doesn't cost much ($12.50). 500 hardcover pages of formulas and diagrams

Any pressure vessel design program will do a good job.  

Don’t design too close to the minimum as someone is already planning to impose higher loads than your design.

RE: bracket stresses

Aybee,
Check some of you technical book suppliers in Australia. In the US it's carried by several. Lincoln should also have a represenetive there.
I know about the shipping to and from Australia, I've purchased several fishing reels from Alvey. Used the slowest method.

(OP)
thanks Unclesyd, I have their Arc Welding handbook ..intend to call their Oz rep...I can tell you are a man of sound judgement if you bought  Alvey reels..Aybee
