Numerical investigation of the effects of structural geometric and material nonlinearities on limit-cycle oscillation of a cropped delta wing

Effect of sweep angle on bifurcation analysis of a wing containing cubic nonlinearity

“…They showed that the type of bifurcation and turning point location depends on the characteristics of the airfoil as well as the parameters of structural nonlinearity. Numerical investigation of the effects of structural geometric and material nonlinearities on limit-cycle oscillation of a cropped delta wing was considered by Peng et al (2011). This study demonstrated that the LCO of the cropped delta wing was not only closely related to geometric nonlinearity, but was also remarkably affected by material nonlinearity.…”

Aeroelastic analysis of wings with isotropic and orthotropic materials in compressible flow

“…This problem was experimentally investigated by Schairer and Hand [23] for a wing formed by a steel plate and flow conditions with fixed Mach number, but with dynamic pressures varying from values where LCO starts to levels for which instability due to flutter occurs. Progressively more sophisticated approaches were used in works presented by Gordnier and Melville [12], Gordnier [13], Attar and Gordnier [3] and Peng and Han [19] for the numerical simulation of this problem. The increment of model complexity used for FSI analysis enhanced simulations quality for cases of LCO with low amplitude.…”

Parametric uncertainty quantification in coalescene flutter

“…viscosity, large deformations or material plasticity, etc. ), seen in references [25,26,27], CFD methods are used to solve the full Navier Stokes equations to obtain the forcing expressions.…”
