WebNov 1, 2016 · The study builds on and extends the major contribution to spherical shell buckling by Koiter in the 1960s. Numerical results are presented for the axisymmetric large deflection behaviour of perfect spheres followed by an extensive analysis of the role axisymmetric imperfections play in reducing the buckling pressure. WebFeb 13, 2024 · Viscoelastic shells subjected to a pressure loading exhibit rich and complex time-dependent responses. Here we focus on the phenomenon of pseudo-bistability, i.e. a viscoelastic shell can stay inverted when pressure is removed, and snap to its natural shape after a delay time. WebThis is especially important for aircrafts and launch vehicles. Cylindrical and spherical shells are often used as elements in such structures. Because of the thinness of the structures, buckling is the most common failure mode. The classical buckling pressure of a complete elastic thin spherical shell was obtained by R.
