TRANSVERSE VIBRATIONS OF A RECTANGULAR CANTILEVER PLATE WITH THICKNESS VARYING IN A DISCONTINUOUS FASHION
A numerical solution is obtained for the title problem by means of the finite element method. An experimental investigation of the problem is also presented for plates of square planform. The agreement between theoretical and experimental values is very good in the case of the fundamental frequency, and reasonably good when the second and third normal modes of transverse vibration are considered. It is concluded that beneficial effects are obtained in the sense that one generates a lighter structural element with higher fundamental frequency of transverse vibration. Hence, the dynamic stiffening is achieved.
