Abstract (2. Language): 
In this study, accurate numerical results are presented for the vibration frequencies of uniform uniax-ially in-plane loaded simply supported, rectangular, angle-ply laminated plates. In-plane loads are chosen as certain ratios of the critical buckling loads of the plates investigated. The Ritz method, along with the dis-placement component assumed in the form of a double sine series, is applied in order to solve the vibration and buckling problems of angle–ply laminated plates, which can not be solved analytically. Convergence studies are presented to demonstrate the accuracies of the results and the effects of fiber orientation angle, side ratios and different materials on the frequencies of in-plane loaded composite plates are investigated.
Abstract (Original Language): 
Bu çalışmada, tek eksenli düzlem-içi üniform yükler etkisindeki tüm kenarları basit destekli simetrik açı-lı-katmanlı kompozit plakların titreşim frekansları verilmiştir. Düzlem-içi yükler incelenen plakların kritik burkulma yüklerinin belirli oranları olarak seçilmiştir. Basit destekli açılı-katmanlı kompozit plakların burkul-ma ve titreşim problemlerine analitik bir çözüm bulmak mümkün olmadığından, problemin çözümünde yer de-ğiştirme bileşeninin trigonometrik olarak seçildiği Ritz yöntemi kullanılmıştır. Sonuçların doğruluğunu göster-mek amacıyla yakınsama çalışmaları verilmiştir. Elyaf yönlenme açısı, katman sayısı, kenar oranları ve farklı malzemelerin düzlem-içi yüklü kompozit plakların titreşimi üzerindeki etkileri araştırılmıştır.
