Extract

The present note is concerned with the flexural vibrations of a thin elastic plate with variable rigidity and having the form of a sector of a circular ring. Plates of this shape have been rather sparsely treated in the literature.

The problem of free vibration of sectorial plates with radial edges simply supported has been investigated by Ramiah and Vijaykumar and by Ramakrishnan and Kunnukkasseril. For the case of a plate having clamped radial edges and the circumferential edges having any combination of boundary conditions, an approximate solution has been obtained by Bhattacharya. The free vibration of annular plates for various boundary conditions are summarised by Leissa. All these are for plates of constant thickness only.
