Dear all,
I am now reading a paper about the stress distribution in pin-loaded orthotropic plates.
The paper 'Contact stresses in pin-loaded orthotropic plates' is written by Prof. M.W. Hyer.
In this paper, the stresses on the boundary of the hole in the plate are given by a complex Fourier series with unknown coefficietns Ak. The unknown coefficients Ak's are determined by a system of algebraic equations: [C]*{A}={B}. A collocation procedure is needed to construct the square matrix [C].
