Mode with a Nonlinear Time Function Approximation Method) linearizing method agree well with classical and analytical solutions. Also it is shown that with considering the vanishing of damping ratio instead of coalescence of first two eigenvalues as stopping criteria in the related program, the instability sets in at a somewhat higher value of λ. Results are also different for different signs of the amplitude of the panel by
applying third order piston theory aerodynamics.
