This is Fig. 1 from the 1974 BOSOR4 paper, "Stress, stability and vibration of complex, branched shells of revolution" by David Bushnell, Computers & Structures, Vol. 4, pp 399 – 435, 1974.
This figure shows many of the computer programs for shells and solids of revolution in existence as of 1973.
Journal papers and reports about many of these old computer programs are cited in the "early papers" section of the long shell buckling "bibliography" document that website visitors can download from this website.
