Zusammenfassung:Vibration-induced fatigue and excessive noise radiation are serious problems of periodically supported curved panels, which are encountered in aerospace and ship structures. A method of analysis to determine multi-supported curved panel frequencies using high-precision triangular finite element is presented in this paper. It presents the free vibration results of a multi-supported finite curved panel continuous in circumferential and axial directions which can be used to compare the results obtained from a current ongoing research related to periodic shell vibration.
