...Yichang Shen; Philip D. Cha; Xiang Zhou In this paper, a simple and efficient method to enforce nodes, or points of zero vibration, on an arbitrarily supported rectangular plate subjected to multiple harmonics with distinct excitation frequencies is developed. This vibration suppression is achieved...

...C. Y. Wang The study of the vibration of thin plates is fundamental in structural design. An excellent source for the transverse vibration of plates of various shapes can be found in the seminal work of Leissa [ 1 ]. Common boundary conditions include clamped, simply supported, or free edges. We...

...Deng Qing-tian; Yang Zhi-chun A study of scattering characteristics of S 0 and A 0 Lamb modes in an infinite isotropic plate with multiple damage is presented in this paper. Both plate theory and the wave function expansion method are utilized to derive the scattered wave field of a single damage...

... results in different accuracies and requires different amounts of computation. Different methods on the eigenfrequency computation of a beam and a plate carrying arbitrary number of concentrated mass/spring are presented and compared. The advantages and disadvantages of these methods are analyzed...
