TL;DR: In this article, a method for the prediction of dynamic characteristics of rectangular plates with cutouts is described, based on the use of variational principles in conjunction with finite difference technique.

TL;DR: In this article, a variational technique has been used to minimize the total energy of the stiffened plate and the derivatives appearing in the energy functional are replaced by finite difference equations, taking into account inplane deformation of the plate and stiffener and the effect of inplane inertia on the natural frequencies and mode shapes.

TL;DR: In this article, the frequency parameters for orthotropic plates have been predicted by using a finite difference technique and compared with known results, and the predicted frequency parameter is a function of the interval variation parameter, β.
