Abstract

This paper presents the dual boundary integral equations for the buckling analysis of the shear deformable cracked plates. The domain integrals which appear in this formulation are transferred to boundary integrals using the dual reciprocity method. The plate buckling displacement and hypersingular traction integral equations are presented as a standard eigenvalue problem, which would allow direct evaluation of the critical load factor and buckling modes. Several examples with different geometries and boundary conditions are presented to demonstrate the accuracy of the proposed formulation.
