[PSUBS-MAILIST] ABS Hull calulation Spreadsheet - How to use.

[Cliff Redus via Personal_Submersibles]

Scott
Each column in the ABS spreadsheet is a different case.  The pressure hull on the R300 is shaped like a coke bottle.  As such, there is a 30" diameter cylindrical  section and a 10" diameter section.  Both needed to be designed. Material properties of HY-100 :

| Yield strength |  689 MPa |  100000 psi |
|  Shear modulus (typical of steel) |  80 GPa |  11600 ksi |
|  Elastic modulus (typical of steel) |  205 GPa |  29700 ksi |
|  Poisson's ratio |  0.28 |  0.28 |

A few questions. What is the difference and reasoning for the 30" elliptical section and the 10" elliptical section? How do you get the material properties of HY-100 and other materials? Is there a source sheet? Thanks,Scott Waters

Concatenated version for spherical heads

1) Open the excel spreadsheet
2) At top, click "Enable Editing" if you see that option
3) At top, look for a message about macros being disabled and click 
"Enable Content" so you can enter your own data
4) Click the "Spherical and Elliptical Heads" tab at the bottom.
5) Lines 5 through 9 is where you enter material properties. It is 
preset for A516gr70.
6) Lines 10 through 22 are for hemisphere heads.
---- Line 11, enter diameter of head in column C
---- Line 15, enter thickness of head in column C
---- Line 22, read maximum allowable pressure

Note: when you enter a number in a cell you MUST click in another cell 
anywhere in the spreadsheet for the calculation to take effect.
