Abstract

The nodal line finite difference method developed earlier by the author has been successfully applied to bending analysis of rectangular plates. In the present work, the method is extended to solve plane stress problems of rectangular plates. The analysis deals with the in-plane displacements and requires the solution of two simultaneous second-order partial differential equations. These equations are transformed into two simultaneous ordinary differential equations which in turns are cast in two simultaneous nodal line difference equations. Numerical results obtained by the finite strip method and this indicates the applicability and the power of the present technique.
