    if you have any questions regarding the shell and the imperfection sensitivity, let me know !

      could you please do something regarding buckling of plates ?

      Dear Pr, could you please make something about "thermal buckling" composite plate and cylindrical shell. Thank you

    Can you explain that how to apply circumferential non uniform pressure on cylinder (we have equation) surface?

      divide the cylinder into different section using the partition tool as shown here:

      @@hnrwagner Thank you for your reply. If force is sinusoidal shape( not with time) varies along circumference, it should be discretized the cylinder or any other method available?

    I don't understand how GNA result is higher than LBA, isn't KDF something lower the critical bukling load ? But in this case 28 kN / 27 kN > 1, am I missing something ?

      Happens sometimes for composite shells nothing unusual in my experience.

    kudos, to the poor guy who had to build this thing.

      the low knockdown factor shows, that it is not easy to build so thin shells.
