| Abstract: | The paper outlines a numerical method for stability analysis of cylindrical shells with initial imperfections. We solve a
nonlinear buckling problem for a cylindrical shell with variable wall thickness under surface pressure. The imperfections
of the shell are modeled as the first buckling mode. A probabilistic approach is used to determine the reliability against
buckling of the cylindrical shell with the probability density of initial imperfections represented by uniform distribution,
triangular distribution, or Gaussian distribution |
