Fatigue and Fracture of Thin Metallic Foils with Aerospace Applications

Fatigue and Fracture of Thin Metallic Foils with Aerospace Applications

Metallic honeycomb structures are being studied for use as thermal protection systems for hypersonic vehicles and as structural panels in other aerospace applications. One potential concern is the growth of fatigue cracks in the thin face-sheets used for these structures. To address this concern, t...
