Abstract :
The physical weak-discontinuous problem of an interfacial crack between homogeneous materials and functionally graded materials (FGMs) is studied based on Reissner´s plates considering transverse shear deformation effect. The higher order crack tip fields of homogeneous materials and FGMs regions are obtained by the eigen-expansion method. The normalized stress intensity factors(SIFs) and stress distributions near the crack tip are computed and compared by means of the higher order fields and singular fields, respectively.
