dc.description.abstractU ovom radu primenjena je metoda dinamičke krutosti za analizu slobodnih vibracija sistema koji se sastoji od kružne cilindrične ljuske i kružnih i/ili prstenastih ploča. Pri formulaciji dinamičkih matrica krutosti korišćena je Flügge-ove teorija ljuski, kao i Kirchoff-ova teorija tankih ploča. Na osnovu razvijenog programa u Matlab okruženju, urađeno je nekoliko numeričkih primera. Rezultati za sopstvene frekvencije dobijeni primenom metode dinamičke krutosti upoređeni su sa rezultatima dobijenim pomoću komercijalnog programa Abaqus zasnovanog na metodi konačnih elemenata.sr
dc.description.abstractIn this paper, the dynamic stiffness method is used for the free vibration analysis of assemblies built up of circular cylindrical shells and circular and/or annular plates. Flügge's shell theory as well as Kirchoff's theory of thin plates were used in the formulation of dynamic stiffness matrices. Based on the Matlab code, developed for this particular purpose, several numerical examples were presented. The results for natural frequencies obtained using the dynamic stiffness method are compared with the results obtained using the commercial finite element method - based software Abaqus.sr
