Experimental Determination of Buckling Strength of Stiffened Panels

In engineering application, the use of stiffened plates made of composite structures has increased over the last few decades due to its high efficiency in terms of high stiffness to low weight and high strength. Generally, the physical structure of stiffened plates is subjected to compressive in-plane loading and a continuous increase of these load results in buckling which in terms causes structural failure. Experimental work is carried on stiffened and un-stiffened plates with the composite materials have been carrying with a view to predicting the buckling load by fabricating it with glass fiber with epoxy resin by pattern molding technique. Analyses are performing to investigate the effect of strength on the stiffened panel using both isotropic material and fiber reinforced composite material on stiffeners
