Abstract:

This study presents the double Fourier cosine series method for solving the flexural problem of Kirchhoff plates resting on an elastic foundation of the Winkler type. The problem is a boundary value problem represented by a fourth order partial differentialquantum. For the case of simply supported edges, the Dirichlet boundary conditions are identically satisfied by double Fouriercosine series if the plate centre becomes the origin of the Cartesian coordinates. A Fourier cosine series assumption for theunknown deflection function and the known load distribution results in an algebraic problem for the unknown Fourierparameters of the series; which is solved to obtain the deflection function. The paper presents general solutions for deflection andbending moments for arbitrary transverse load distribution and specific solutions for the deflections and bending moments for thespecific cases of point load at arbitrary point, and at the centre, uniformly distributed load over the entire plate and sinusoidalload. It was found that the solutions obtained in this study were exact solutions and this was because the double Fourier cosineseries used for the deflection shape functions were exact shape functions that satisfies all the Dirichlet boundary conditions.Furthermore, the trial solution was made to satisfy the boundary value problem at all points in the solution domain.
