Re: [PSUBS-MAILIST] Best source for structural calculations

[Marc de Piolenc <piolenc@archivale.com>]

Let me see if I can be a bit clearer.

Of course our field of interest draws on many fields of science, 
engineering and technology. I have all the basic science and engineering 
references, plus some semi-specialized books on naval architecture and 
so on. My own specialties are aeronautical engineering (lighter than 
air) and aero-propulsion, especially ducted propulsors. I also have a 
long-standing interest in shell structures and in ferrocement shells for 
both housing and boats.

What I'm looking for is a text that treats submarine structures 
SPECIFICALLY, starting with the basic system of forces acting on the 
pressure hull (which in most manned subs will be the major structural 
member) and progressing from there, first to the exact mathematical 
relations used in stress analysis OF THIS PARTICULAR TYPE OF STRUCTURE 
SUBJECTED TO THIS SYSTEM OF FORCES, and from there to the approximate 
formulas needed for preliminary design.

I have what I THINK is a valid picture of the forces on the pressure 
hull, and I've been accumulating literature on axisymmetric structures 
under combined - external pressure and axial compresion - loading, but 
there's longitudinal bending to be taken care of, too, and I want to 
make sure I'm on the right track, because I'm basically self-taught in 
structures.

Thanks in advance.

Best,
Marc
