โœฆ Synopsis

The in~uence of localized imperfections on the buckling of a long cylindrical shell under axial compression is analysed by using a double scale analysis including interaction modes[ This leads to a system of coupled complex non!linear di}erential equations with discontinuous derivatives[ We propose analytical formulas to predict the reduction of the critical buckling load[

Stability of imperfect elastic cylindrical shells which are subjected to uniform axial compression is analyzed by using the finite element method. Multiple interacting localized axisymmetric initial geometric imperfections, having either triangular or wavelet shapes, were considered. The effect of a
