Optimized crenellation designs for fatigue life improvement of metallic airframe structures
, 2017 Fatigue of airframe structures is a critical concern for the safety of aircraft. Serious accidents due to the accumulation of fatigue damages in airframes are by no means rare cases in history. Nowadays to ensure the structural integrity of the aircraft periodic inspections are performed on the airframe structure to detect and repair fatigue cracks ...

Core crush criterion to determine the strength of sandwich composite structures subjected to compression after impact [PDF]
, 2008 In this study a core crush criterion is proposed to determine the residual strength of impacted sandwich structures. The core of the sandwich is made of a Nomex Honeycomb core and the faces are laminated and remain thin.
