AbstractIn this research a new method based on the method of fundamental solution has beenproposed for eigensolution of partial differential equation PDEs with constantcoefficient The first set of results has been presented for the Helmholtz equation Inthis method the approximate solution is expressed as a series using exponentialfunctions as the fundamental solution Constant coefficients of this series areevaluated through an especial discrete transformation In this research afterintroducing an especial flexibility matrix a new criterion was proposed for evaluatingeigenvalues and eigenmodes After developing an algorithm for eigensolution of theHelmholtz equation this algorithm has been extended to other importanteigenequations in solid mechanics including free vibration of plates and buckling ofplates
