摘要：

The phenomenon of the local loss of stability (buckling) earlier discovered by the authors experimentally was simulated theoretically. An approach to assessing the load-carrying capacity of circular cylindrical shells with periodic dents is presented. The authors show that application of the linear theory or solution of the problem in the nonlinear formulation with few iterations (when calculating the subcritical state) results in large quantitative errors. To get more accurate and reliable numerical data, one needs to solve the problem of the nonuniform subcritical state in the nonlinear formulation with many iterations. The local buckling loads determined numerically are lower than the experimental values, i.e., the errors are on the safe side. The loads characterizing the overall buckling are either close to the experimental values or also lower. © 2004 Plenum Publishing Corporation.
