BUCKLING ANALYSIS OF COMPOSITE CYLINDRICAL SHELL STRUCTURE USING FINITE ELEMENT ANALYSIS
Abstract: When designing cylindrical shells one should consider not only the strength problem in service, but also the buckling problem. Cylindrical shells such as thin-walled structures are susceptible to buckling when subjected to static and dynamic stresses. The vessels are exposed to dynamic sea conditions depending on their usage. The functional failure of a pressurized composite vessel or a composite pipe in the form of leakage or weeping of the contained …

Buckling and vibration of plates by hyperbolic shear deformation theory
Abstract: Hyperbolic shear deformation theory is used to determine the natural frequencies and buckling loads of elastic plates. The theory takes account of transverse shear effects and hyperbolic cosine distribution of the transverse shear strains through the thickness of the plate, hence it does not require shear correction factor. Governing equations are derived from the principle of virtual work. The closed-form solution of a simply supported plate subjected to in-plane loading …

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 …

Abstract: The crashworthiness in automobile is stated as the capability of a passenger car and its interior arrangements to safe-guard occupants from harm. Whenever an accident occurs, the passengers in the car can be injured due to one of the following reasons: (1) excess acceleration force; (2) physical injury from contact with injurious surfaces, and; (3) exposed to fire, smoke, and chemicals released during accidents. Thus effective crashworthiness design must take …
