About Free Interfacial Vibrations of Thin Elastic Circular Cylindrical Shells

Free interfacial vibrations of closed and non-closed infinite cylindrical shells composed of two semi-infinite orthotropic thin cylindrical shells with different elastic properties are studied. Using the system of equations of the related classical theory of orthotropic cylindrical shells, dispersio...
