SUMMARY:Shell buckling - without those ‘imperfections’ - Prof Chris Ca
 lladine\, Structural Mechanics\, CUED

DESCRIPTION:     When buckling experiments were conducted on thin-walled c
 ylindrical shells under axial compression\, in the 1930s\,\nit was discove
 red that the classical buckling analysis of the 1910s gave very poor predi
 ctions of the empirical results.\n     Following the work of Koiter (1914 
 -1997)\, the conventional wisdom about this discrepancy between Theory and
  Experiment has been that the buckling process is "imperfection-sensitive"
 \, and that imperfections are unavoidable.\n     In this talk I shall take
  a different view\, based on two specific novel experiments.\nIn brief\, I
  claim that "imperfection-sensitivity" is a solution to the wrong problem.
