Buckling Strength of Metallic and Composite Plates with Small and Large Hole at Different Locations
Abstract: Most of the aircraft structures will experience a buckling phenomenon due to compressive loads. The cutouts like system small and large holes, lighting holes etc. are introduced in the aircraft structure at different locations for accessing aircraft inside and for passing electrical wires and ducts. The stress rises around these holes due to removing area in the panel and buckling phenomena will become further critical in aircraft structures. The cutouts …
