FREE VIBRATION OF PIEZOELECTRIC CYLINDRICAL SHELLS

Ding Haojiang Guo Yimu Yang Qingda Chen Weiqiu(Dept.of Mech.,Zhejiang University,Hangzhou 310027.China)  
Three displacement functions are introduced to represent each mechanical displacement according to the 3-D theory in this paper,By expanding the displacement functions and the electric po- tential in orthogonal series,the free vibration equation of piezoelectric cylindrical shells satisfying SS3 boundary conditions can be obtained.The equation was solved by utilizing Bessel functions with com- plex arguments.Results are presented graphically as well as in table,and compared with those of other references.Some frequencies that were missing in Ref.[9]are discovered.
