Abstract

Presence of cracks or similar imperfections can considerably reduce the buckling load of a shell structure. In this paper, the buckling of thin conical frusta with cracks under axial loads has been studied. At first, a frustum without any imperfection has been analyzed. In continuation, sensitivity of the buckling load to the crack presence with different length and orientation has also been investigated. This procedure has been investigated on three types of frusta with different heights and constant semi-apical angles. Some effective parameters on buckling have been studied separately and the required data for analysis have been gained through experimental tests. The finite element ABAQUS software has been used for the numerical analyses.
