| Abstract: | Differential equations of free/forced vibrations of rectangular stepped plates are established by using singular functions, their general solutions are solved for expression of vibration mode function and frequency equations on usual supports derived with W operator. Conclusions of this paper may be suited for plates with different boundary conditions. |
