  Buckling Strength of Metallic and Composite Plates with Small and Large Hole at Different Locations

  By Sundaresan Poovalingam, Rajeshwar Baddam, Ravindra Kiragi

  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 …

  Predicting Elastic and Plastic Stress Concentration Factor using Notch Strength Analysis

  By Ravindra Kiragi, Sundaresan Poovalingam, Indradeep Bhadra

  Abstract: Structural sizing is getting more sophisticated as weight and cost of any structure is important. Weight optimization is a key player in enhancing business revenues and reducing fuel consumption for a greener planet. Thus, millennial designers attempt to develop weight optimized structures, while meeting structural stiffness, strength and integrity, and safety requirements as specified by international certification agencies. This can be achieved by innovative analyses approaches, which predict realistic factor …
