Effect of Geometric Imperfection on Buckling Strength of Cylindrical Shells (original) (raw)

2007

Abstract

In this research paper, effect of geometric imperfection on buckling of cylindrical shell subjected to different types of loadings has been investigated using Finite element analysis and compared with analytical model by Donnell and semi Empirical model based on experimentation [1,2] of a perfect shell. In finite element analysis Newton Raphson and Arc length methods are used. Based on the presented results conclusions can be drawn concerning the shell behavior and its sensitivity to different loadings.
