【Abstract】 A study for an orthotropic circular cylindrical shell subjected to axially loaded is present in this paper. For shear diaphragms at both ends, the resulting characteristic equations about pressure and frequency are given. The effect of shell’s parameters (L/R, h/R) and material properties on the free vibration characteristics have been studied. Differences between Love-Timoshenko, Donnell equations and that of Flügge theory are examined too.更多还原
