Stress Concentration Factors for Stiffener Run-Out Regions
Abstract: Stiffener and stringer run-out is a common design feature followed in aircraft structures such as fuselage, wings and empennage. The run-outs are necessary due to specific structural and interface requirements. These run-outs act as a stress raisers similar to any geometric discontinuity in these structures. The stress concentration factors (SCFs) are available only for stiffener with 90 º run-outs (also known as shoulder fillets) in the literature. In the absence …
