I found that I need AIAA Journal Vol.3, No.10, 1965 by Rossettos and Sanders, "Toroidal Shells Under Internal Pressure in the Transition Range". Anyone have a copy?
I believe I somewhat found my own answer. From Roark, 6th Ed., Table 28, Case 5 (Table 13.1 in 7th Ed.). Toroidal shell with internal pressure gives max σ1=(pr)/(2t)*(2R-r)/(R-r) which is same as BDM equation at θ=-90deg. However, I would like to find what reference Roark used. I suspect...
I have performed stress analysis of aircraft systems previously where I have utilized Boeing Design Manual BDM-6845, Piping and Ducting. In it, it accounts for a stress factor on the hoop stress at tube bends, Section 3.5, (2R+rsinθ)/2/(R+rsinθ). I am now in need of an open source reference for...
