Static and dynamic analyses of anisotropic plates with corner points

Abstract

The present paper also deals with the application of the Ritz method to the determination of the natural frequencies of a rectangular anisotropic plate with a free corner formed by the intersection of two free edges. The resulting algorithm permits the analysis of anisotropic, orthotropic and isotropic materials. Accurate values can be obtained by incrementing the number of orthogonal polynomials, and the entire algorithm can be implemented on a personal computer. The software constitutes a useful tool in design work because of the great number of vibrating anisotropic plate problems that can be solved.
