The Effect of Dent Imperfection on Conical Shell Behavior Under External Pressure

حسین شوکتي- عباس تيمورزاده- توحید قنبري- , 5th National Congress on Civil Engineeringn the basis of extensive buckling tests and numerical buckling analyses for conical shells it became desirable to provide a recommendation for the most reliable evaluation of stability limits for imperfect cones subjected to external pressure. This paper reports on different simulations including non-linear FE analysis results and discusses the related effects of dents as well as the critical buckling load of such structure
