The fatigue life is essential for every aircraft to rectify several damages occurred on it. In this project we have done fatigue analysis of the aircraft wing Boeing 737 series wing. The detailed modeling of aircraft wing structure made by using the software CREO parametric 2.0. The stress analysis of the wing structure is carried out. The stresses are estimated by using the finite element approach with the help of NX-NASTRON to find out the fatigue life and safety factor of the structure. This Project describes about the finite element analysis of spar, ribs of a wing. The objective of this study is to reduce the weight to the maximum possible extent. The response of the wing structure will be evaluated. In this study prediction of fatigue life, safety factor, strength safety factor will be carried out.

Zusammenfassung der Kapitel (Chapter Summaries)
The first chapter introduces the concept of fatigue in materials, emphasizing its importance in aircraft design and the implications of cyclic loading on metallic components. The second chapter delves into the design calculations, outlining the process of estimating the load acting on the wing using flow analysis in Ansys 12. It also presents the meshing process, loading, and boundary conditions applied to the wing model.
The third chapter focuses on the results of the fatigue analysis, including displacement, elemental stress, fatigue life, strength safety factor, and fatigue safety factor for both 50mm and 20mm ribs. The chapter analyzes the data and provides insights into the performance of the wing structure under pressure loading.
