Impact of structural uncertainties on the buckling strength of cylindrical GLARE panels subjected to uniform compression

The objective of this article is the investigation of the elastic buckling strength of cylindrical simply supported GLARE (GLAss REinforced) panels subjected to axial compression using probabilistic analysis methods, so that the effect of uncertainties associated with material properties and dimensi...
