Effect of Geometric Imperfections in the Shape of Buckling Form on the Reduction of Load Capacity of Cylindrical Shell

The approach to numerical analyses was changed by the introduction of Eurocodes. The EN 1993-1-6 standard allows taking into account imperfections on the shape of a buckling form from a linear elastic bifurcation analysis. The article analyses the first ten forms of imperfection from a linear elastic bifurcation analysis on the reduction of the capacity of a cylindrical shell. Calculations were made using finite element methods.
