RE: [PSUBS-MAILIST] ABS Hull Calculator concerns.



Just another find is that Line 88 in Cylindrical Shell calcs the formulas between Column C and column D differ.

These should be the same.  Affects I min.  Had me going for a bit there with oversized stiffeners required.

Jon, Ray,

 

The ABS Hull calculator as downloaded is showing Yield strength of 70,000 psi but it should be 37,700 psi according to ASME.  70,000 is the UTS.

This does not have a great effect on the Cylindrical shell calcs but certainly does on the Heads.  I think it should be altered so it downloads correctly.

Please check to see if I am right.  Hugh
