Influence of stiffener eccentricity and end moment on stability of cylinders in compression.

An Overview of Buckling and Imperfection of Cone-Cylinder Transition under Various Loading Condition

“…The load eccentricity additionally has been shown to relatively influence the shell buckling load and considered as another class of imperfection. Literally, numerous works have been carried out to address the issue, with few examples discussed here for cylinders (Eglitis, 2011;Eglitis et al, 2009;Simitses et al, 1985;Stuhlman et al, 1966), for cone (Błachut and Stanier, 2012) and stiffened cylinder (Block, 1968;Singer and Rosen, 1976). Besides that, the non-uniform axial compression (Libai and Durban, 1977;Papadopoulos and Iglesis, 2007) and uneven support distribution (Guggenberger et al, 2000;Teng and Rotter, 1992) may effectively influence the shells buckling strength and act as imperfection.…”
