Natural frequencies of twisted rotating plates


Journal Article

A detailed comparison is presented of the predicted eigenfrequencies of twisted rotating plates as obtained by using two different shape functions. Primarily, rotating twisted plates of two different aspect ratios and two different thickness ratios are considered. The effects of rotation are included by using a "stress smoothing" technique when calculating the augmented stiffness matrix. In addition, the effects of Coriolis acceleration, contributions from membrane behaviour, setting angle and sweep angle are considered. The effects of geometric non-linearity are briefly discussed. Finally, results of a brief study of cambered plates are presented. © 1984.
