Özet

This study is devoted to some specific free vibration analysis of thin composite plates based on discrete singular convolution (DSC) approach. As the first analysis, a parametric study is performed on the basis of number of lamination, boundary condition, and orientation angle of symmetrically laminated composite plates. As the second, the effects of material type, boundary condition, and stacking sequence on the modal characteristics of laminated plates made of E-glass/epoxy, Kevlar/epoxy, and carbon/epoxy are investigated. Thirdly, linear modal characteristics of fiber metal laminates are specifically analyzed due to their common use in aircraft design. Hopefully, the results presented in the article may be practically of interest for engineers and designers. This study displays the applicability of the DSC method for real-life problems.
