🌊 Deep-Sea Pressure Hull: Lame Stress, Buckling and Collapse Depth (2D)

Cross-section of a sealed sphere or long cylinder at depth, squeezed by seawater pressure, with the wall coloured by its safety factor and buckled into lobes when it fails. Set the depth, shape, radius, wall thickness, modulus, yield strength and imperfection knock-down, and see the pressure, the wall stresses, the yield and buckling collapse pressures and the collapse depth. The compressible hydrostatic pressure, the Lame equilibrium, the ring buckling eigenvalue and the yield-buckling crossover are checked numerically, with four in-page numerical checks.
