Fonksiyonel Değişimli Malzemelerle Kaplı Seramik Silindirik Panelin Titreşim Analizi

In this study, the vibration of ceramic cylindrical panel covered by FGM coatings composed of zirconium oxide (ZrO2) and titanium-aloy (Ti6Al4V) is investigated. First, a sandwich cylindrical panel covered by FGM coatings is designed. After the derivation of basic equations are found expression for the frequency of ceramic cylindrical panels covered by FGM coatings. Discusses the influence of coatings profiles, sandwich shell characteristics, the radius-tothickness ratio and the core-to-coating thickness ratio on the dimensionless frequencies for FG and homogeneous sandwich cylindrical shell
