Abstract |
|
Structural integrity is an important factor to be considered when it comes to the safety of aircrafts. Structural integrity is the ability of a structure to withstand a designed service load resisting structural failure due to fracture, deformation and fatigue. In this current work, stress analysis of a wing box with a cutout in the bottom skin for fuel access is carried out to find the critical region where there is a possibility of fatigue crack initiation. Crack arrest capability of the bottom skin is determined by the damage tolerance analysis. Static testing of the scaled down model of the bottom skin is carried out using the universal testing machine. |
