Main Article Content
Abstract
An analytical method is presented to study the bending vibration of a cantilevered, laminated composite rectangular panel having blended layers. The panel (plate) having blended layers is modelled as a laminated plate in which the outer layers have subdivisions with non-identical fiber orientation. A finite element program is also coded to clarify accuracy of the present method. In numerical examples, the natural frequencies computed by the proposed method show very good agreement with those from the FEM code. Use of this fast and accurate method is suggested in vibration design, for example, optimization of fundamental frequencies.
