An Excel spreadsheet compares the following four bounds on the yield onset pressure due to Interbay imperfections in thin-wall monocoque and ring-stiffened cylindrical pressure vessels: • Bodner-Berks method [1] • Galletly-Bart method [2] • Gordon’s simply supported method [3] • Gordon’s clamped end method [3] Because the first two methods are based on Donnell's equation of equilibrium, they are applicable only for shallow shells—that is for relatively short thin-wall cylinders whose critical buckling mode shapes are characterized by a large number of circumferential lobes. (Reference [1] claims greater than 8 lobes.) This restriction does not apply to the second two methods because they are based on Morley’s equation of equilibrium [4] rather than Donnell’s. Technical documentation is included.

...Calculate and optimize the following: Minimum plate thickness (DNV/DNVGL-OS-C101) Minimum section modulus of stiffener/plate (DNVGL-OS-C101) Minimum shear area (DNVGL-OS-C101) Buckling (DNVGL-RP-C201) Fatigue for plate/stiffener connection (DNVGL-RP-C203) Compartments (tank pressures) are created automatically. Pressures on external hull (or any other generic location) is defined by specifying equations. You can optimize single plate/stiffener field or multiple.

...It also includes a range of features that facilitate the visualization and examination of various relevant quantities e.g. velocities, stress, rate of deformation, pressure, and finite strain. Folder contains a separate application, which illustrates analytical solutions of growth rate spectra for buckling and necking of a single viscous layer.
