In this work, the stress intensity factors for a bi-material interface crack are obtained using the weight function method which has been well established for cracks in homogeneous bodies. The weight functions are determined using the finite element technique based on variational principles to determine the displacement fields for bodies with unbounded strain energy. The selection of approximate singular fields for the weight functions are discussed.
