RE: [PSUBS-MAILIST] Steel Pipe Hull

Jay,

 

Thanks for pointing that out...it's an important note.  However, you can plug the data from the charts into the "hull Calculator" spread sheet located at

http://www.psubs.org/designguide/ABS_Hull_Calculation__Rev_12_17_2004.xls to get an idea of how different materials will react to external pressure.

Jon,

Please note these charts are for design of vessels that will experience an internal pressure not an external pressure like a submersible.  Other modes of failure such as buckling predominate in submarine hull design so these tables are not applicable for a PSUBS (other than the VBT or compressed air tanks).
