    I have added here a repository for the excel file with all the equation for spherical shell buckling from the video:

    Dr. Wagner, thank you for this video. For the shallow sphere, you used the clamped boundary conditions (no displacements and no rotations on the equator). What boundary condition did you use for the complete sphere? Thank you

    hello sir ,thank you for this video,i have one question about how can a hollow sphere under internel pressure be modeled with abaqus,

      do you have a reference (paper, book,...) I am not sure what you mean

      @@hnrwagner ,a thick sphere with inner radius Ri = 0.1 m and outer radius R0 = 0.2 m. The module
      of elasticity on the inner surface of the cylinder was taken equal to E0 = 21 MPa and the
      Poisson's ratio being constantν=0.3. The internal pressure Pi = 1MPa and the
      external pressure is zero Pe = 0MPa.
