Abstract

Aircraft wings encounter multiple forces during flight, like thrust, drag, and abrupt variations caused by storms. Although these forces aid in maintaining overall stability, they can also cause the growth of cracks and expand over time, a process referred to as fatigue. The resulting lift, drag, and pressure distribution on the wing have been analyzed using computational fluid dynamics in ANSYS. These loads were then incorporated into the wing model to evaluate the shear and equivalent stresses. Cracks growing on the aircraft wing surface. The wing surface manufactured from AL2024-T3 alloy was investigated when subjected to non-preoperational multi-axial cyclic loading. This fracture mechanics analysis employed two methods: experimental calculation and Numerical simulations.
