The effect of curvature on transient analysis of laminated composite cylindrical shells on elastic foundation

Öz:
This study presents the effect of curvature ratio on transient vibrationanalysis of simply supported antisymmetric thick cross-ply laminatedcomposite shells (LCS) on elastic foundation. In the analysis, thefoundation is modeled with two parameters. These models arePasternak and Winkler models. The equation of motion for laminatedrectangular shells resting on elastic foundation is obtained throughHamilton’s principle. The analysis is achieved in Laplace domain. Byusing modified Durbin’s algorithm, calculations are transformed fromLaplace domain to the time domain. The numerical results arepresented in the form of graphics .

Elastik zemin üzerine oturan tabakalı kompozit silindirik kabukların zorlanmış titreşim analizi üzerine eğriliğin etkisi

Öz:
Bu çalışmada, elastik zemin üzerine oturan basit mesnetli antisimetrik çapraz-katlı dizilimli tabakalı kompozit silindirik kalın kabukların (LCS), zorlanmış titreşim analizi üzerine eğrilik oranının etkisi sunulmaktadır. Bu analizlerde, zemin iki parametre ile modellendi. Bu modeller Pasternak ve Winkler modelleridir. Hamilton prensipleri ile elastik zemin üzerindeki tabakalı kompozit dikdörtgen kabukların hareket denklemleri elde edilmiştir. Analizler, Laplace alanında elde edilmiştir. Modifiye Durbin yöntemi ile çözümler Laplace alanından zaman alanına dönüştürülmüştür. Sayısal sonuçlar grafikler şeklinde sunulmuştur.
