[PSUBS-MAILIST] Abs calculator

[abyssalobsession@gmail.com]

I have been in the process of putting my rough sketches into actual hard blueprints.  The only thing that really confuses me is the design of the stiffeners.  I understand what the different dimensions represent, but I don't know what their relationship to each other is.  How does web thickness, web width, flange width, and flange thickness affect each other.  Why does having stiffeners too beefy make their max pressure go down?  And last but most important if I choose to use smaller stiffeners than what is most efficient for the hull thickness, are their any significant risks as long as I am operating within the maximums.  I know these would probably require a degree in engineering, but I am still a few semesters away from this kind of stuff though.  I appreciate any insights.
