Abstract
The authors put forward a numerical approach to determination of nonlinear bending stability of a long flexible cylindrical shell with geometrical imperfections The shell wall imperfection in the form of bulging in long halfwave is modeled using a software package for finiteelement analysis Prebuckling and postbuckling behavior of an imperfect shell in bending is studied The critical normal stress in the shell compression zone is plotted vs the imperfection amplitude The bending stability region is determined for a shell with geometrical imperfections
