The Spectral Method for Moving Load Analysis of Thin Plates

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. The first part of the paper describes the spectral method formulated on the basis of matrix operators. The application in plate analysis is presented using an example. The other part elaborates on dynamic analysis and moving loads. An example illustrates the application of spectral matrix operators. 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. The presented approach is general in its formulation and can be easily adapted for analysis of any other structure.
