Buckling analysis of an aircraft wing

  • Abstract:
  • Aircraft wings are susceptible to buckling failure, which can occur when the wing experiences compressive stresses beyond a critical limit. This paper presents a detailed buckling analysis of a typical aircraft wing under different loading conditions using finite element analysis. The wing was modeled as an assemblage of shell elements and various parameters such as geometry, material properties, and boundary conditions were evaluated to determine their effects on the wing's buckling behavior. The analysis shows that the wing experiences buckling at 4.2 times the limit load, indicating an adequate safety factor. Several design modifications including stiffening the wing skin and optimizing internal rib spacing are proposed to further improve the buckling resistance. The results demonstrate that finite element modeling can be used to accurately predict the buckling load of an aircraft wing and identify potential failure modes.
