Bifurcation Analysis with Aerodynamic-Structure Uncertainties by the Nonintrusive PCE Method
An aeroelastic model for airfoil with a third-order stiffness in both pitch and plunge degree of freedom (DOF) and the modified Leishman–Beddoes (LB) model were built and validated. The nonintrusive polynomial chaos expansion (PCE) based on tensor product is applied to quantify the uncertainty of ae...
