WebNov 24, 2015 · Abstract. The stability of a thin flexible plate confined inside an inviscid two-dimensional channel is examined using a nonlinear eigenvalue analysis method. A new … WebApr 1, 2013 · This study illustrates the mechanism of modal coupling in cantilever plate flutter using the full Theodorsen airfoil theory within the linear framework. An accurate, pseudo-spectral method is employed to calculate the fluid loading and the eigenvalue problem is solved numerically following the Galerkin procedure.
Flutter instability of a thin flexible plate in a channel
WebAug 1, 2007 · In this paper, we have developed a new theoretical model that enables the modelling of the flutter of a rectangular cantilevered plate in axial flow. We have assumed that the plate deflection is two-dimensional and immersed in a three-dimensional potential inviscid flow. Starting with the equation of motion of the plate, the stability analysis ... WebApr 1, 2011 · We study the effect of adding discrete structural mass on the linear stability of an otherwise homogeneous cantilevered-free flexible plate immersed in uniform axial flow.The methods of Howell et al. that mixed numerical simulation with eigenvalue analysis are simply extended for the present study. An ideal two-dimensional flow is assumed … highmark spending account benefits card
