WebGradient-based optimization, via the adjoint method, is needed to realistically enable the reliability-based design of a nonlinear unsteady aeroelastic system with many random and/or deterministic design variables. The adjoint derivatives of a time-marched system entail a cumbersome reverse-time integration, and so a time-periodic spectral element … Webfamily of Newmark’s algorithms (Newmark 1959), the Wilson-θ method (1973) and the HHT method of Hilber, Hughes & Taylor (1977). The Newmark method with its commonly used values (γ=2β=0.5) is the most accurate unconditionally stable scheme (Dahlquist, 1963), but results in excessive numerical oscillations.
