Abstract
This paper deals with the buckling analysis of stiffened circular plates through numerical simulation techniques using Abaqus 6.5. In the present numerical investigation, the effect of aspect ratio (R/T) of a stiffened circular plate on the buckling strength is determined for different mode shapes. Three different geometric shapes, namely T, I and HAT, are considered to reinforce the plate by way of stiffeners. For all the cases studied in the present investigation, a circular plate with a radius of 0.5 m is subjected to in-plane loading. The boundary conditions are such that the edge is fixed but released in the radial direction during buckling. The results of the analysis for the radius-to-thickness ratio of the plate, in the range from 200 to 250, with four intermediate steps are presented in the form of buckling loads corresponding to different mode shapes in tabular and graphical form.
