Abstract

The effect of geometric nonlinearity has often been seen as negligible in comparison with the imperfection sensitivity of cylindrical shells. For the most widely study case of a uniformly compressed cylinder the loss of strength due to geometric nonlinearity only accounts for about 15%, while imperfection sensitivity can account for a strength loss of up to 80%. This paper describes a parametric study of a bracket supported silo. Due to the bracket attached to the silo wall the stress field before buckling is highly nonlinear and the strength of the perfect silo is greatly reduced, but while the geometrically nonlinear analysis does lead to a significantly reduced strength compared to the linear bifurcation analysis, geometric imperfections do not play a major part in the loss of strength. The effects of geometric nonlinearity will be shown on a wide range of geometries and the imperfection sensitivity will be shown in two examples.
