To prevent catastrophic oscillatory failures in aircraft wings, a vibration analysis is imperative. A specific Circumferentially Asymmetric Stiffness Configuration is implemented and fully described in http://www.aeroway.ca/Taperedwing.htm
A new Dynamic Finite Element (DFE) formulation is developed to calculate the natural frequencies and modes of wings composed of advanced super light composite materials. This enhanced method provides highly accurate solutions compared to classical Finite Elements.
