Abstract: | ![]() The influence of torsional ridigity of the stiffeners on the buckling of reinforced aluminum-alloy panels has been investigated. Experimental results reveal that stiffener torsional rigidity must be introduced in the analysis of compressed panels, for, if the stiffener has a closed cross section, the stiffener shape may change the buckling mode shape essentially and increase the critical load considerably.José María Mínguez was Postgraduate Student in Engineering, Metallic Structures Group, University of Bath, United Kingdom |
