Bu çalışmada kalın kompozit silindirik bir panelin hareketli yük altındaki dinamik davranışı Ritz çözüm fonksiyonları ile incelenmektedir. Panelin dinamik denklemleri virtüel iş ilkesi ile elde edilmektedir. Düzleme dik doğrultudaki kalınlık etkisi 1. mertebe kayma deformasyon teorisi ile dikkate alınmaktadır. Ritz çözüm fonksiyonlarının kullanılması sonucu elde edilen zamana bağlı hareket denklemleri implisit Newmark metodu ile çözülmektedir. Hareketli yükün farklı hız değerleri, silindirik panelin farklı eğrilik oranları ve farklı sınır şartları için parametrik çalışma yapılarak panelin değişen dinamik davranışları incelenmektedir.
