000004872 520__ $$2eng$$aBuckling of the wing of a unique aircraft structural design concept, the joined-wing, is examined in a stochastic context. This non-traditional design might induce coupling between buckling and aeroelastic instabilities; furthermore, the geometric, structural, and aerodynamic nonlinearities inherent to this design increase the potential of ignored or poorly modeled uncertainties to promote unexpectedly severe response. We emphasize modeling stochasticity in the wing joint and the wing roots because of their importance in determining the response characteristics of the coupled structure. Gaussian randomness in the Young’s modulus is introduced into an existing deterministic finite element model at these locations to approximate the effect of uncertain joint fixity. Plans are described for future modifications that will facilitate a more extensive stochastic analysis.
