TL;DR: In this article, a simple analytical approach which allows for the prediction of the natural frequencies of circular plates with stepped thickness is proposed, which can be used in the construction of high frequency transducers.

TL;DR: In this paper, a nonlinear diffusion type problem in doubly-connected domains of complicated boundary shape was solved with variable transformation and conformal mapping methods. But the results were in good agreement with numerical predictions obtained with a finite element code.

TL;DR: In this article, a general yet quite simple approach is proposed to deal with the title problem, assuming that the plate edges are elastically restrained against rotation, and numerical results are presented for orthotropic configurations as well as for some isotropic cases.
