Panel Flutter Analysis of Cross-Ply Composite Plate Utilizing Minimum Angle Tracking

최소각 추적 방식을 이용한 직교적층평판에 대한 플러터 해석

An alternative panel flutter approach utilizing minimum angle is presented. The minimum angle is the lowest value among the angles between modes i and j at a certain pressure condition. This method utilizes eigenvectors rather than eigenvalues. Cross-ply composite plates are considered in this study. A remarkable result of this investigation is that the angle always dropped gradually to zero for all presented examples
