Moving load analysis using spectral method

This paper shows an application of the spectral method in dynamics of structures for the special case of plate under the action of a moving load. Spectral method formulated on the basis of matrix operators is described. The example includes Dirichlet and Neumann boundary conditions and complex loading since it is simply supported - free plate under the action of a moving force. The boundary conditions have been imposed using Lagrange multipliers. Presented theory of spectral matrix operators is especially suited for strong formulation.
